My engine builder decked my block today.
It looks like he took a lot off.
Its a b18c1 gsr.
How do I check the clearences?
Whats the clearance supposed to be at?

You'll have to check your P2V and see if you are good to go....

ok well if he knows, then you know too. How much did he say he took off?

boostedteg4dr

.006 he says there is .011 left. but i dont know how much the first machinist took off if any.

if you think he took off that much, maybe you should be worried about piston 2 head clearance.....LOL!

I think you're reading that wrong. A stock GSR has a .030" piston to deck clearance, not including the .029" 3-layer MLS gasket.

The easiest way to check is to put in a rod & piston combo of which you know the exact length of. Then clay the head/block at the quench pads. Google will tell you what OEM dimensions are supposed to be. Just remember to add the gasket thickness. It may be a pain, but its faster than finding someone with a mic big enough, or willing to set some rig up to measure it.
