I tried searching this but i didn't find any answers.

1. Whats the name/part number of the gasket on the header that is put in between the junction where it goes from 4 pipes to 2? I'm trying to find it and the idiots at Pepboys are no help.

2. If i put H22 Type-S pistons, DH racing headgasket, and flat faced valves in my H motor to raise compression, will i have issues with piston to valve clearance or any other issues? If so, how would i go about solving that, by modifying the pistons themselves?

Any help would be greatly appreciated.

 

1. Don't remember the pn, but I thought they're just called exhaust manifold gaskets. Sometimes they are referred to as donut gaskets due to their shape. A local dealer should be able to find them for you; they're only a couple bucks a piece iirc.

2. Are you on stock cams? Flat faced valves shouldn't change the p2v at all as the overall valve length is the same, it's a matter of how far the cam profile is pushing the valves out (lift). I'm not a p2v expert nor do I have the experience to give informative advice beyond that, but I assume with stock cams you will be fine. What is the height of the DH hg?

 

Evertime i go in i say i need an exhaust manifold gasket and they look at me like i'm dumb. Thats what i thought they would be called too, but apparently its not that simple.

I would be running skunk2 stage2 tuner cams with the setup, so it wouldn't be a stock piston to valve clearance. The DH racing headgaskets measure at .0014. So i'm under the impression the Type-S pistons would stick out farther than usual with that thin of a gasket and that aggressive of a cam. Anyone know?

Illustration #8. They call it an exhaust pipe gasket. Part# 18212-SB2-961, two are required. Majestic sells them for $3.86 each + some ungodly amount for S/H. San Leandro charges $1.06 each with lower S/H prices.

Thanks alot!

Also, anyone know about the piston to valve clearance i mentioned before?

 

there was a cam thread on here a little while back; it may have more info about p2v clearances.
