Hi I couldn't post this anywhere else yet.

I took my head to a machinist a long time ago and I think I remember there being 3 studs for thermostat housing. They may have been bolts but either way they are missing. Could anyone tell me the size of the bolt or stud that I need there?
And is there one for the crank pos sensor also?

You're remembering correctly.

The 1G thermostat housing (3x) and CAS (2x) both utilized studs to mount them to the head. They are all M8 x 1.25mm pitch. Four of the five are specified at 25mm long and are part number MS041428; the last one is 35mm long and part number MS401431. Reason for the difference in length? The longer stud was used as a mounting point for the engine lift bracket or "engine stay", whichever you want to call it, that mounted to the throttle body and head via that stud.

Man I really appreciate your help. I could not find that from my searches. Thank you.
