Getting the head machined tomorrow, and Im wondering if I should have the head shaved while I'm at it? What would be the power gain be vs the loss in engine life? An how much would I shave the head if I did it?
I don't think I'd shave the head unless you are going all out with the engine; like a turbo and cam. Cause you will have to re-do a lot of the engine measurements I believe. And it also depends on why you are pulling the head off. Blown HG, low compression in one cylinder, bent valve?
For the price I'd just get the head resurfaced. (What I did) Once you do all the work the engine will be more powerful anyway, because you will feel accomplished about getting the engine in better running order.
it's called Squish Area..
Compression Ratio , But then again , What head gasket thickness was installed, ??, This all plus flow and deeper than tech forum..
Anyways , alway know before you remove metal YOU cannot replace.
Blowen Head gasket is a end result of another problem, Why did it get over heated ?? or was it Poor Coolant eat ??
