That can’t be right? 1.667 comp height is zero deck on a stock stroke magnum. That’s exactly what I’m running.
(3.58/2)+6.123+1.667
Magnum deck height is 9.58
It’s correct. The only discrepancy Ive found is the compression height listed as 1.612 on multiple pages. Either way when using an LA piston (1.667) in a mag block it will be proud of the deck a bit. .008-.011 with nominal numbers.
