oh and can anyone tell me what the stock head is so i can figure how much they shaved off

I wouldn’t be too concerned about marks on the head you highlighted, they are due to the block and stock gasket having a waterway and no waterway in the head, in other words the mark is due to the head having no waterway. Some supra owners have drilled through the head in that location to try and increase the cooling efficacy, not sure of the results or why Toyota didn’t continue the waterway through to the head. The surface finish on the head is normally left to a competent machine shop, lots of info in these links. http://www.aa1car.com/library/ar996.htm

Stock cylinder head measures 116mm ( 4.567 inch) thick.

no shit. how do you think the rest of the head looks?

Difficult to say looking at the pic`s, there seems to be some surface scratches I wouldn’t expect to see after machining. As I said I will be picking up a head next week from a machine shop I've used often over the years. I’ll post some close up photo's of the head surface which may help you compare yours to. Some heads in this link.

You should pm Ij. Or one of the forum specialists. They will know off the top of their heads. I do not have that 411 or I would give it up.

It’s the bottom line of my post No22.

and thats from were the valve cover meets the head tho were the head meets the block right

i went out and bought a caliper to measure and it comes out to about 116mm even

does that sound right?

and i called the shop and they said they have worked with peaple putting mhgs on and that all i have to do is spray the head gasket with cooper. do you guys think that sounds right?
