Which piston design is better for the stealth head? Flat top(zero deck), dome or reverse dome? for and 10-11 to 1 NA application?




What size is the engine ?




440 stock stroke. I have KB flat tops at zero deck with 452s now. Lookin to go 915s or Stealths.




Stealths are closed chamber heads that are cast at 84cc's, which lend themselves to work well with a flat-top piston at 0-deck. Use a .040 gasket, and you'll have a quench motor that should check in right around 10 - 10.5:1 depending on valve relief's and a few other variables. My 451 has OTB stealths on it and I've been happy sofar.
