Engine stud boil over

Posted by Jeff on March 27, 1998 at 19:49:28

Here's my problem, thanks for your suggestions.

I have mated a professionally rebuilt short block and machined head using copper/asbestos show gasket, glued down with the "purple stuff" (permatex sealant from Brattons).New studs used coated with anti-seize.All torqued through multiple hot/cold cycles to 55 (I've done it at least 10 times).When engine gets warmed up (motometer shows minimal if any red) I get head water draining up through studs # 3 & 6, and engine seems to run rougher.
Had similar problem with last engine but I'd blow the motometer red through the top pretty quickly as hot exhaust would blow into the water jacket.Solved that with proper torque of head.Problem now seems different.
Should I pull studs and wrap in teflon tape?
I look forward to suggestions.thanks.
