The inner spring I posted about on my E Street heads in a earlier post is actually called a dampner, looks like a inner spring, my bad. Thanks for the clarification Scott.
We usually dont use a 268xe for a pump gas build past 9.5::1. Actually seen some detonation in the low 9s lugging it. You will get some heat dissipation with the aluminum head upgrade...IMO not enough for 10.5:1. There really is very little gained from running that small of cam with high compression. Unless you really like the smell of race gas...suggest to your engine builder to try for upper 9's if the cam is staying.

Hey have you considered any Indy heads? I seem to never hear the name mentioned just trick flow and stealth. I wonder where the trick flow and stealths are made? I’m gathering cost maybe a factor just curious ?
