im doing a set of heads for a board member so i figured id throw up some pics as i work on them

up first is some valve deshrouding and chamber smoothing along with some chamber reshaping, the chamber reshaping pics will be limited though

first up s a stock shot around the intake valve





and now heres a deshrouded shot




im on my laptop and took the pics with my cell so i might have one or to of them mixed up dam screen on this laptop is hard to see outside

ill post more pictures as i progress on the heads.
once im done withthe iron head top end i will be doing a 3400 topend

 

and the start of some chamber mods and polishing

this is just a ruff cut and ruff pollish
and u can start to see some work starting in the bowl area of the intake valve





lol the picture order is screwed up but u get the idea

 

since im done working for the day ill post these up and show u basically what is going to happen in the bowl and guide area and ill post up pics of the actual work when i do it tommorow

basically the edge leading up to the valve guide will be cut back like this


and then the back side of the bowl around the guide will get blended in

thispicture is a really rough cut as i start to work on the guide area


basically it ends up finishing something like this ( this isnt a finished guide bowl area btw)

 

compare to a fully stock intake port on the right side

 

what do the stock heads flow, and what kind of numbers could you expect out of your ported ones?

 

i shoudl be able to tell u in a few days im waiting on some parts to come in so i can finish my flow bench, if the parts dont ge here in time i will have another set to do i can flow

 

Looking good so far, did you start on the intake manifolds yet, and did you try fitting the beehive springs on there? Or do any work to the actual port on the heads? Also, if you can be finished by thursday let me know, my grandmother says she could pick them up on her way home from work between 3 and 4, if not its no big deal, would just be convenient, but I would rather you do a good job and take your time finishing the stuff than rushing through the work just so she can pick them up thursday. Also any idea on whether or not you might be able to make it out to pittsburgh on monday or sometime that week? I just about got my radiator out to put the new cam in before I came out here, I just need vice grips to disconnect the trans coolant line without breaking it(the nut on the fitting stripped, and since its wrapped around a line I can't use my special sockets for stripped heads, the ac radiator I just cut the lines on it, but only thing keeping the rad from coming out is the trans lines right now. Also, can the CSI be removed without causing issues? I broke the line removing it because the haynes manual was less than clear and at the time I had no idea wth I was doing...

 

i dont think ill be done by thursday , and i havent goten as far as the valve springs yet

if got 2 out of 3 ports done on one head, its a lil slow going since alls i have here is a 10 gallon compressor i can only port for so long since the compressor runs while im using the die grinder and every 10-15 mins i have to stop to let the compressor cool down


not to mention ive been dicking with the dam neon all day, new coil pack came in but the dam connector dont fit i must have contacted about 10 junkyards today trying to hunt down the conector

 

Alright, long as you can be done by friday night. So any chance you can come up my way on monday to help me get it all back together?

 

looks like we are all from PA lol. I'm in the middle of the state near York. Anyway, what tooling are you using to do this? A Dremel? And second, what would you suggest to use for iron heads?

 

hey man give my cell a txt later im not sure ill have them done toniht might not be done till tom still have to fix the od dam neon.

 

im usin an air powered die grinder and a dremel, i do not suggest using only a dremel as it would take u forever to do it

die grinder with carbide cutters and tootsie roll sandin rolls are the best

 

Well, if you can make a trip up sometime next week monday-friday to help put the cam in and get the engine together you could just bring them then, but what all do you have complete so far? And did you try fitting the beehive springs yet?

 

one head is fully done the other is about 50%, im oing to try to get it done tongiht but i still need to goto dmv today to get my pa dl, ill know about the springs in a lil bit though im messing with them now

 

behives arent going to fit without the right retainers

 

I'll check if I can find any retaners for under $50, as for the rocker arms, best solution there is to just put them on the 2.8 studs with a washer right? And I still need to know if you can make it up sometime next week or not..It would be a lot more cost effective than driving to your place just to pick the parts up, if its a matter of transportation, I might be able to swing down, bring you up to pgh, and take you back...not sure yet though.

Edit: I should be looking for 3x00 valve spring retainers right?

 

no the 3xxx stuff uses a smaller diamiter valve stem they will not fit the iron head valves yeah as of right now i may not have transportation the neon is still dead god dam thing belongs in the junkyard

theres some links over on 60*v6 for the right retianers to use im not sure if they are posted on thirdgen

 

Haha, I bet you my buick could give it a run for its money....my mom just admitted to my face that the car is indeed on it's way to the graveyard(she heard it run a couple minutes ago when I moved it).

 

Looking pretty good.

I have been working on boost ported 3800 heads and have a set of 3.4 irons coming up. Amazing the amount of time/work it takes to get the heads even to where Gen2 flows lol.

I have the 3800 heads flowing over 200cfm@.400" and 224cfm@.650, stock on my bench was 160@.650". With manifolds, they are flowing over 180cfm even.

Can't wait to see how much skills have improved since having the flowbench on this next set of iron 660's.

 

what are you using the dremel for ? is there something that you cant use the die grinder for? i just got a die grinder and i intend to do some mild cleanup work and gasket matching to my cast iron heads... carbide cutters and sanding rolls all i need? my die grinder came with some stones are they any use for this??? thanks for any help-ROn

 

I NEVER use a Dremmel. I have a standard die grinder and a long-nose grinder and use 1/8" and 1/4" shaft stones, sanding rolls and carbide burrs of varying lengths (2", 4" and 6" long) and even have 7" extensions to get into manifolds even further. Make sure you get the double cut burrs as single cut is for aluminum.

For the one-time deal, you could probably get away with stones only, but it will take considerably longer to remove material (although in your case of just cleaning the castings, they will work fine).

 

project89, how close to Pittsburgh are you? I live just south of Morgantown, WV and was looking for someone to port and polish my heads for my 3.1L. I was just curious as to how much you would charge, so I can compare to prices around here at various machine shops.

Also, 3rd gen RS, are you just putting an OE cam in your V6, or are you putting something more beefy in? If so, could you please tell me what? I'm trying to squeeze every ounce of power out of this V6, while still keeping it naturally aspirated. Thanks!

 

260 grind from delta, deff not stock specs either
Not putting in either, its already in there and the engine has already run, just working out a couple vac lines, put PS pump back in, alternator back in, fill coolant and shes done
Also he lives in johnstown, or outskirts anyway.

 

john is exactly right but i like to use the dremel in the chambers for the polishing work its a nicer lighter tool for doing actual polishing work

 

pm sent


also look in 3rdgens live build thread there are 2 videos of us starting the car up in the bottom of that thread

 

thanks for the info-Ron

 

I just run the die grinder through an air regulator. Set it to 50-60psi (trigger closed) or so,and you can literally stop it with your hand.

 

I use a flap wheel on the die grinder at low pressure, occasionally sanding rolls to get in tight spots.

The most gains aren't from chamber work so i don't put too much effort into them.

 

i have another question, should i get one of those regulators?? i have a cheap old compressor that was given to my dad and then to me so i have no idea what psi its at... thanks again

 

qft the biggest gain in the chamber is deshrouding the valves polishing the chamber helps a lil bit ( compared to the time spent doing it) but it is a good thing on a motor with high compression to help eliminate hot spots in the chamber helps with pre ignition

 

so with 9.5 to 1 compression i should leave the chambers alone huh? thats good cause i dont wanna mess it up anyway

 

it dosent hurt to do it put the time can be better spent elsewere deff deshroud the valves though look at my first few pics in the thread

 

For sure. I have been only able to gain a couple CFM, even with de-shrouding and extensive spark plug area work. I have tested ports side by side, one ported with no de-shroud and the other with and pending application it can be a waste of time. Iron heads definitely need the chambers smoothed moreso than aluminum heads diue to their inferior casting quality.

 

as of right now im just gonna gasket match all the ports and smooth out the casting imperfections on the chambers of my 813 heads im not going to try to unshroud the valves cause i dont wanna mess it up if its only worth a couple cfm.... that sound about right or is there anythingelse i can do that will make a difference?
