What's that stuff, Prussian blue?
Put the head on with out gasket, check for gaps.
Dude, so sucks!
Your sitting on one of those problems, brand new gaskets suck?, or machine work sucks, both are new!!! One of the worse problems.
This assumes you actually put in any or all of the head bolts, and torqued any or all of the bolts;) or that you did not bottom out the bolts, or hydraulic them, etc...
Or you put on the head gasket correctly, not sideways or any thing;).
Trying to add levity since 05.
