Whats Up Guys, I'm buying a set of edlebrock 68722 Headers and y-pipe off a guy, the sell I believe is just for the headers and y-pipe. My question is what other hardware will I need in order to successfully install everything, Like gaskets, bolts, etc stuff like that?, Basically anything that I need to install everything.... I need to know asap so I can get everything because I'm having a friend install everything and I want everything done as soon as possible....

Also where would be a good place to get these things as well Please help guys!!!!!

 

anybody

 

Any Help At All Guys?????????

 

I know it's exciting to do the first mod. THere are tons of threads and posts about exhaust and what to use but here you go

gaskets- don't go cheap. The best are dead soft aluminum and will cost you aroud $30-$40 depending if you get Percys or Mr gasket brand. Mr Gasket are at some parts stores and Percys are either on line at the usual suspects (jegs, summit et al) and also at speed shops.

then, you will need header bolts. I actually determine whether i use a hex head bolt or allen head based upon the proximity to each pipe. Since this is your first dance then you probably won't have a wide selection around your garage so look at the header compared to the hole and if you can fit a socket or box wrench, great. if not, then get the allen head bolts. These can be had at any parts store as SBCs are common

next, does it have a spot for an O2 already in it? If not, you'll need to make provisions for that (used headers are all of a sudden not so cheap are they)

you will also need to verify that the y pipe is in fact for that header. Do that BEFORE PAYING and make sure ot fits. he should provide the hardware to attach the y to the collectors. That leaves your connection from the Y to your cat converter (or cat delete pipe) and you'll probably need an adapter pipe and a couple clamps for that. Again, all available at the parts store

you'll also need 8 new spark plugs (hey, you're right there so why not)

Oh, headers go in much easier with the starter removed

good luck and welcome to the first of what will be a ton of mods in your life

 

whatever gaskets u use, i would elongate the holes to match the headers. When i used edelbrock header gaskets they were ridiculously smaller than the headers.

 

you will need spark plug wires with 90 degree boots. Shorter plugs too. Try Bosch 7985

 

Don't buy those headers. You will have problems. Get Dyno Don Headers. They are the best out there.

 

why would he have problems? I have Edelbrock TES for 2 years now and they have been fine. Not everyone has the money for Dyno Dons either.

 

just make sure you buy new header gaskets and donut gaskets

 

thanks for all the input guys!, so to be clear, I need a new set of gaskets, some bolts and how do I make a spot for the o2 sensor is that expensive??

 

You cut your old wire and add a about 6 inches of new wire . If you get a code 13 then that means that you may need to get a heated o2 sensor. You should be ok tho.

 

Well the tubes are 1 1/2 and 1 5/8. You can't get the spark plugs out easily and its easy to burn the wires.

 

Thats what most headers for small blocks are.

 

Wrong! Do your research. SLP's are not like that.

 

I know that Slp's are 1 3/4. There is nothing wrong with 1 5/8. That is actually better for low end torque. You want velocity/speed in your exhaust. You don't want your primaries too big either. You will lose low end.

 

Thanks for all the info guys, I actually decided not to buy the used edlebrocks and I ordered A pair Of Hedman Headers Part #68470 and Headman Y-Pipe Part #17478 It only came out to a total of $308.67 which is only 9 bucks more then what I was about to pay for the used pair. I figure this was better being that it comes with all the hardware I need to install everything. Are these hedman headers and y-pipe any good????....... Let me know guys....

 

Did the Edelbrock's come with the air injection? just wondering. Those headmans should be descent. Either way it should be an improvement over stock stuff.

 

They work great and there are no problems with spark plugs, Mine are even angle plugs and I have no trouble changing them. Don't use the gaskets they come with, Dead soft aluminum or copper are the best I've had. The only thing I changed on them is the outlet on the Y pipe, I didn't want the 2 1/2 inch outlet so I cut where the pipes merge on the Y and had a 3 inch mandrel bent pipe made and installed that. Good luck.

Mark.

 

You will not lose low end torque. You will have a big gain across the board. We did the actual testing here in SoCal.

I say save your money and try to find some SLP's used for cheap.

 

No it didnt come with any of the air stuff, they where ceramic coated though! which is why I wanted them so bad but I think its just safer to order the hedmans from summit because I know everything matches and I have everything I need to install

 

Cool then thats what Ill go with then, not that I have a choice I already ordered it...... I hope everything flows well once I get my hedmans installed and get my magnaflow cat back installed....... I know this is alittle bit off the topic but what do you guys think about the magna flow cat back system part #16829????

I only ask because thats the one I have (not installed yet) and was wanting to know is it a good cat-back system????

 

There is always a big debate on mufflers on this site, It's all personal taste in sound because there is not a whole lot of difference on power between the different brands, I think the Magnaflows sound good but I have the Force II Flowmaster exhaust on mine mainly for sound( I did a lot of searching for a good sound online) but I'm not a fan of duel pipes sticking out under the bumper, Mine has a 3 inch single outlet hidden under the bumper cover, But there again It's all about personal taste.


Mark.

 

I hear you, I actually like the two pipes sticking from the back, in my opinion it gives the car that muscle look lol...... and I was under the impression that diffrent cat-back systems would produce more power over the other, and as far as sound I just hope this magna flow is not loud like some exhuast systems I have heard on third gens, I like mine to be queit but give a little roar when going fast

 

The Magnaflow is not real loud, it has a good tone. I should have said there is not much of a difference in power between the different brands. There are a lot of tests out there that show differences in flow numbers but when they do dyno tests they are all very close. I always tell people to get the muffler that sounds the best to them. All personal opinion.

Mark.

 

those will come with header bolts but you still need a decent gasket. I used hex key bolts on a couple locations with the hedmans because of proximity to the primaries. You may wish to pick up a set. You can always return them unopened if not needed but be glad you have them if you decide to use them.

you will also be going to a shop to have an O2 bung welded onto the drivers side collector (standard O2 wiring will reach so no worries)

those are the painted headers and will be stinky for a day or two as it burns off and then get rusty but so what??? You aren't restoring a show car and they will last for you

you should get some heat tape because the y pipe just about rests on the oil pan and also the tranny cooler lines will touch it so wrap the tranny cooler lines near the pipe as well

again, don't go cheap on the gaskets. dead soft aluminum.

 

How do I know which set of gaskets I need, I'm looking on summit's website and They have multiple aluminum gaskets made by Percy....... I know the heads on my car are tbi swirl ports(if this info needs to be considered when picking a set)

 

the muffler i have seen that produces the most torque and hp is the borla xs. Supposed to be very quiet tho.

 

the headers are round so go with that. You may want to check with your local adv auto or autozone. They might have Mr Gasket dead soft aluminums and they are $5 cheaper and you don't pay the silly summit fee or shipping

Take the $20 you'll save from the summit fee and shipping and spend it on a chrome open air element while you're at the local shop. They'll have one in stock, the box will be all dusty so offer them $10 less than the price on the sticker...........they'll take it. I used a 14 inch by 2 inch high
