Re: Cylinder Head Specs

There are no specs for that, at least not that I've ever seen or heard of. There is a spec for the combustion chamber volume so you could "cc" the chambers and thus determine if the head has been resurfaced previously. Knowing that, you can rely on past experience of others who have safely had their heads done - I expect some folks will be along with how much they got away with, or didn't. The safest route is to only resurface if it is absolutely essential, and if you do, by all means check for valve clearance before you reassemble. You'll find plenty of posts here about techniques for checking valve clearances to the roof of the combustion chamber. Actually measuring the clearance will tell you how much room you have to work within for resurfacing.
