Has anyone successfully shaved 243 heads down to 57cc?! Flow numbers after porting are 250/350, very impressed! Just looking at a way to bump compression a little more! Running E85 on a 414ci stroker..

Thanks!

You can increase ruffly 1/10 of a point of compression for every 0.006 you shave compression depends on a number of factors like pistons cc / -cc with E85 you can run 12 13 14 to one compression no problem provided your cooling system and your camshaft are up to task.

Cam motion Patrick G. custom grind 246/250 .626"/.626" 113LSA +4

Decided to stick with 60cc, this will keep my compression at 11.8:1...
