2" head gasket

i know you are probably right since you did it yourself but with the compression calculator i use it says 0.032 out of the hole.... is you block's been decked before?

I dont know if it work like this but if you add the a d15b7 headgasket 0.048inch ---> 1.2192mm to the deck height (207.45mm) so it gives 208.6692 and put 0.0 as the headgasket... theoretically it put the piston .015 in the hole... now we just need to know if the valve will clear...

can the b7 headgasket stand up that kind of compression...?

Bone1

which compression calc are you using?

someone didn't get the memo, D15 = 207.00 mm deck height

.45mm = .018"

.032" + .018" = .050"

PS the block was never deck either, just a 150,000 mile D15B8 block I got for free.

Hint: 2 OEM Z6/Y8 HG's at .070 total equal about 12.0:1 compression, but better clay the valves.

so the deck height is 207.00 or 207.45... i saw both

I'm the person who measured both

The 207.45mm when I posted it, I told everyone is was close but not exact as the crank was still in the lock.
