Jeff-
You could be getting leakage throught the head gasket from the water passages into the head stud holes.I always use some sealer (permatex) on the edges of all the holes in the headgasket which do not have copper rings to seal - this also helps stop seepage on the driver's side edge of the gasket from the water passages shich are close to the edge.
Good luck
: 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.
