2mm redblock headgasket

If the head was machined 1mm in total, the final CR would be 9.5:1, that's totally and completely fine with a stock turbo and tune with 15psi and premium fuel.
One of the race cars I play with is 9.5:1 and 30psi with a GTX2860, it's totally fine with it. You will be fine using a stock HG.

I checked the piston is .60mm above the block I have a 1.8 mm gasket could I fit this

That is a lot more than 0.254mm...
Are you converting these units from inches, or is the metric system your measurement system?

With the pistons sticking out that high, you'd want something like a 1.5mm head gasket for a good squish distance of .035in(0.89mm). The 1.8mm head gasket would work though, and that would be at about where the factory squish ends up.

With your measurements changing so much, I'd recommend REALLY knowing what the values are before making decisions.

That's not what OP wants. OP wants to commiserate about long lead times for non-stocked parts. Y DO U GIB UNSOLICITED ADVISE?!?!?! OP DOES NOT WANT TO BE TOLD HE IS MAKING THE MISTAKE!!!
 
The mesure were from the machine shop I remeasure today

Cylinder head measurements from rocker cover mount to head gasket surfaces
Is 145.11mm

Piston stick out is .60 mm

I have a 1.8mm when tightened head gasket
 
There's no chance a valve in an 8V redblock is ever going to hit the piston short of a timing failure. The intake and/or exhaust valve would have to be open 10mm or more while the piston is going from the exhaust stroke to intake stroke, which is insane.

My V16T cam is interference, when I was setting up the timing belt, I had to turn the crank backwards after a piston was stopped by a valve. It's had the head cut a couple times and the block decked. That was with a stock head gasket.

But with what numbers? The measurements he posted are in clearance. Done. If they’re correct anyway.
