Your pistons mentioned at the end of your post. I have seen different letter number designators on the speed pro pistons in older posts - what else is there besides H116P ? @67/6barracuda thank you!
They determine how far down the hole they are. Be sure to do you research. I believe there’s three different h116 piston to pin heights to set your piston depths. The h116cp have a compression height of 1.660.
