Big Block Cylinder Heads "915 vs 906"

Tx,

The only 'Back-in-the-Day' 383 Pistons that had a true positive deck height without
decking the block, were offered by 'Forged-True'.

They offered a 'special' 383 Flat-Top Piston, with an extended compression height
for the 1968 and 1969 '383'.

Exactly what I was driving at-thanks for the "heads up"...pun intended. I know I can purchase a custom piston that would clear up all the issues with being below deck (or have the decks equalized) or even use a domed piston (which for some reason, I'm not a terribly big fan of--no real idea why), but I've been conditioned to believe one of the best friends of a well built engine is close quench, and doing that with open chamber heads is a bit tricky compared to running a zero deck flat top, with a closed chamber type head.

but I want it to be you don't believe! I'm used to it.

I dunno--numbers look a little peaky ;)
