Thanks again
I’d say that is going to pretty close to 10:1 with 670 heads. Like that other post says, that is likely more than 10:1 by the time you deck the block to get a better quench. I usually have the deck cut a minimum of .015” to get those pistons to about .010” to 015” below the deck. Your new set up often start out .025” to .030” below the deck.

Probably would have been better to get the optional 28 cc dish, then you could run those smaller cams.
