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?
The standard answer is you need to check for your application but generally the KB400 does still have valve clearance notches they just put a raised dome that fills some of the dead space in the combustion chamber... The dome will impede flame travel & may lead to less than ideal combustion but you need to do something on a 383 to raise the C/R & a dome offers more gains than losses...
