Yup...the lower end is a done deal at this point...balanced and assembled. No cam yet though and I can always change the head gaskets if need be.




the KB is a step head piston , what is the distance between the step head and the open part of the chamber ? That piston was designed to mimic a closed chamber head when setup properly , you chose the worst people KB made for that application , but probably because it was the only one they had.

I had my hands in a build with 452's and step head pistons , Diamond made me these to get 9.5 with 89cc head.




A flat top 0 decked will get you 9.5
