Does anyone out there know what the head spec were for a 70-1/2 RSS 350 (10:25:1) Camaro would be? Especially the cc's. I believe the part number is E21 70 8947041. I am in the process of getting this motor stroked to a 383. Any recommendation on compression ratio?


Thanks,

Mitch

041 heads are 64cc with either 194/150 or 202/160 valves these are fulie type heads good for higher compression applications

Good info on the heads.. Planning to use these on a 383 stroker. Should I keep the 10.25:1 ratio or lower it?
