T.C. Manifold Studs

[hemibum]

A couple of threads in the head for the exhaust manifold are stripped, others are heading the same way. Can anyone tell me what the drill, tap and Helicoil sizes are, and where to purchase new studs? Thanks.

I can't tell you sizes of the top of my head, but new studs are available from Paul Matty Sportscars, QED and no doubt the other Usual Suspects (Sue Miller, Burton, Chris Neil Sportscars, etc.).

ETA: I think the studs are 5/16" UNC at both ends, but don't take my word for it.
