I am finally going back together with the engine out of my '93. Had the block milled .010 (took .006 to get it flat, no wonder I couldn't hold a head gasket). Stock pistons.
Anyways, my piston protrusion is now .035 to .037.
What is the compressed thickness of a standard thickness Mahle headgasket? I have read everything from .057, .063 to .067.
If it is .067 I am good right? The truck will never spin over about 3K so even .063 would be fine, wouldn't it?
If it is .057, will I be alright? I would love to have the resulting compression (19:1) but is .020 enough clearance? I have read that D-maxes are in the .020 to .025 range...
If you roughly add .003 for rod bearing clearance, .003 for main clearance, .001 for wrist pin clearance, and maybe .005(?) for piston rock, we are down to .008 ish minimum piston to head clearance...
So I guess the main question is what is the compressed gasket thickness and will I be alright at whatever that thickness is?
