what exact parts do i need for this.

ive heard many people say the standard abrasives kits arent worth it because you only use 1/4 of it.

so what type stones etc do i need, how many, and can i use a dremel tool with a low/high speed switch .

yes i have a small 2 hp air compressor if i must use/buy an air powered tool.

i hope to start my port matching tonight if possible.

 

What exactly are going to port and polish??

Your plenum, your intake manifold, your heads, or your cigarette lighter?

 

good call, im shooting for a high performance ported and polished gas pedal.

yes, joke

early Lb9 heads.

Note:

ive seen several responses from people who think i have a TPI when my sig says TBI.

 

Certainly didn't hear that from me. I ended up buying extra rolls the first time, bought a 2nd kit for the 2nd job and came close to needing more again.

Some carbide cutters & burrs can come in handy.

You'll need about 3 or 4 of those "small 2 hp air compressor"s if you hope to keep up with a die grinder.

 

ok so, less mocking, more telling me what i *should* get.

 

if you have a cordless power drill (like from black and decker or whatever) you can just buy carbide cutters, 2 should do, 1 rounded and one conical....like 50$ each....die grinder is easier, but if you have to batteries for the drill you can just keep switching batteries.....put the carbide cutter in...and port away...

 

only thing i have is a dremel heh, i DO havea cordless drill but it sucks.

i also have a very heavy duty corded drill , but thatll be way to heavy to hold up.

im about to shoot for the dremel.

i can get these heads done by a machine shop for 400, plus shipping.

im about to consider doing that, due to the lack of all tools needed. itll cost me 200 in tools to do the job right. 200 more and a machine shop will do it.

then again, with that 400, plus another 400 i can have world products heads.

im about to just save up and get those. that or slap the lb9's on the L03 purely stock and deal with it.

i was only going to gasket match and polish the areas i grinded down. wasnt going to bowl polish or anything of the sort.

that just seems too touchy and precise.

 

Slow,

I thought we went through this once already!

Follow the link at the end of my sig. I wouldn't get the Standard Abrasives kit again, I'd just get the carbide cutters I placed pics of in the thread.

five7kid is right about the flapper wheels but you can buy 3 or 4 separately at most good auto stores.

 

Summit offers a set of three 6" carbide cutters for $50. 6" is good for getting to the area around the valve guide from the intake side but the long shafts are easy to bend. If you do that part first, then when you're done you can cut off the shaft and use it at higher rpms to do the bowl. Or you can spend $100 and get 2 sets of burrs long and short. Carbide is the way to go though.
16 ports is a lot of labor using abrasives.

 

im not really planning on doing the bowl and the valve guides, ...only gasket matching then polishing the areas i grinded down.

 

I would suggest actually porting the bowls and ports because that is where you will see gains. Just gasket matching will do practically nothing because that is not the most restrictive part of the head. You may actually just loose velocity and power if thats all you do. Even if you dont feel comfortable removing/reshaping much material you could go in and remove the casting seams and imperfections. This would probably do more good than gasket matching.

I recently got a book called " How to Build & Modify Cheverolet Small-Block V-8 Cylinder Heads" by David Vizard. It has a lot of info and gives you a lot of the info you need to get the best flow out of your heads. Most of it is not real difficult, just time consuming. This being said I havent done a set of heads yet but will be hopefully withing the next couple weeks. I have watched a set of heads be ported, and have done a lot of reading. Once I can get the carbide cutters and abrasives I need I plan on starting on my heads.

Yeah, do the bowl. along with a 3 angle valve job and a proper back-cut on the valves with the seat moved a little bit further out toward the edge of the valve head than stock. Do the porting first then get the seats ground. You'll notice a difference in power, throttle response and the exhaust note. Put a thin gasket in there too to bump up the CR. You'll be stoked!

 

blah screw it, too much crap i have to buy, too much time thatll take and ill end up messing something up.

i have a 2 hp compressor, which just wont do.

any electric grinder is 100 bucks.

plus parts etc, lets say , 250 - 300 dollars, and for 400 i can get it done professionaly.

i may just bolt the lb9 on stock, and say screw it.. anything is better than the L03 heads. do that and just wait til i get the 800 for torkers cause, ...im getting them anyways, these lb9's were FREE with 16k on them after they were rebuilt.

 

Eek!

I hate that attitude. Even more so because you CAN do this work

Use your brains--rent the electric die grinder!

 

doh! i forgot about renting tools

 

Go to http://www.homier.com/ It may not be the highest quality tool out there, but will do the job. Heck even if it doesnt last through doing a bunch of heads they are 20 bucks a shot(25 w/ shipping). If you are just going to be cleaning up one set of heads I think it will be fine.

that it?? if so ill use my dremel....you sure it wont bog down under load?

 

Dremel won't cut it. Need 1/4" collet. The Homier electric might (you'd need some sort of speed control - several have used a variable ceiling fan control successfully).

Gasket matching alone isn't worth much. Bowls & guides is where you will find flow (and therefore power).

I wasn't trying to be mocking with my compressor comment. I was trying to convey some reality.

 

On that site I think they have dremel type tools, but they also have a "electric die grinder" which has a 1/4" collet. If you do a search on electric die grinder it is the only thing that comes up.

 

I recently bought an air die grinder from Advance Auto Parts for twenty bucks. A set of stones to go with it were about ten bux.

Your 2hp compressor will run a die grinder if you have a 5 gallon or so air tank. It may cycle on and off a lot but so what.

For about 50-75 bux and SEVERAL hours of your time you CAN port your own heads.
It's more labor intensive than money intensive.

That should leave about 350 in your pocket for other improvements.
Get the 3 angle valve job and undercut the valves, buy a new set of valve springs,seals, retainers and have the heads surfaced to make sure they are good and flat.
After all that you still should have about a hundred in your pocket.

 

Understood. He asked if he could use his Dremel instead.

 

I wasnt disagreing(man this site needs a spell check feature) with what you said. I was just expanding a little.

Harbor Freight has a router speed control that will work with an electric die grinder. They put them on sale every few months for $13.

 

or you could assemble this...Per RB..

 

well, I have been using my drill and my carbite cutters for now and it really works great! I could use my die grinder but, the drill just has more nuts. when I start to polish I will use the die grinder because it is lighter and turns more rpms.
