I may have messed up here.....

I normally use the 20-24cc dished pistons in my builds. I have the mains honed, and the decks square-decked to give me a piston up out of the deck by .005". I use the chamber size to set the static ratio and that can vary by intended use. The idea is to get the pistons within .035" if the head with the 1009 gasket with the static I want. That's how I do it - but others go about it differently. I love the cam choice. I've used the HR LA version before, and the B/RB flat tappet hydraulic version at least 5-6 times.
