Quote: So with the dome of the KB 400 are there any issues with valve clearance or?
If I don't zero deck the block and just slap on a set of Edelbrock 84cc heads, .040ish head gasket and KB 400s what would be CR be?
If you don't zero deck it the pistons will likely be around .030 in the hole and only give you 9.43 with a .040 gasket or you could use a steel shim and be around 9.87. Zero deck and a .040 gasket would be 10.11
Cool, would there be any chance at that point with the pistons interferring with the XE274 cam?
No, but you should still check to see how much clearence you have.
