Would anyone happen to know the thickness of a stock 3TJ rrsp head? Trying to determine weather mine has had a skim or not.

Shirley you need to know the height or volume of the combustion chamber ?

Every single stock v4 head ive measured have been the same as most engines usualy are too, I dont like relying solely on combustion chamber volume or depth due to the fact if valve seals have been cut too much or a few times, or aftermarket valves such as pattern or stainless valves then head cc can change, hence the reason ive always gone by head thickness

however if we have stock head thickness + head cc then it is more reliable as can use both measurements to calculate it properly
