Wrong Head Gasket - Head Machining question

[Silent Smith]

Hey, I took my head off due to a bhg and noticed the head gasket was missing like 6 or 7 coolant passages. I plan on replacing the hg with a toyota one and going to 74 ftlb.


Now if I have the head skimmed do I have to competely dissasemble the head? Think theres a big possiblity of the head being cracked due to the blocked passages?

I've asked too many questions lately but stuff keeps popping up

Sometimes when you are looking at the gasket and block and head, it may look like something is not right. But...many times the passages are not suppose to go all the way through.

Sometimes they are blocked to send the coolant where its supposed to be.

Yes that partial blockage affects the flow for the better.

The little triangles between the cylinders are supposed to be all blocked on one side?
