They are the edelbrock 118cc heads made for gm's zz572 crate motor. I want to run a thicker cometic head gasket but I keep reading about quench and how I might actually make detonation worse by opening up the quench. I am going to see if Valeko can port the chambers and lose a few cc's while he is installing the inconel valves.

Those roots blower intercoolers, do seem to be a pretty good restriction.
I made 7lbs boost with blower at 7% under. When i changed the engine combo, lowered static, changed heads, added intercoolers, i had to be at 8% over to see psi. Being that i changed several things, hard to say . Did i lose boost because the heads flow better? Air temp cooler? Restriction of the intercooler core ? I really dont know.

No kidding...!! Everyone seems to have a different opinion on this. Especially in blown builds. It sure would be an easy way to get me to upper 8's or 9-1 since the heads have to come off anyway for valves.

Don't spend the money on the chambers wait till you want to up grade the heads to something better. There is a set of CNC brodix heads on ebay with Inconel valve came off a boat freshwater cooled. Don't know if they are better than what you have. Think 2100 ish per set. OBO They look very good.
Flat top piston will run cooler less surface area.

My pistons are flat tops with a 3cc valve relief. Any idea how thick a head gasket they ran on the 1075? If I could run a thicker gasket that would be so.... nice!! Mine are a compressed .030 stock. Some .060-.080's would make a big difference.
