Howard, I'm afraid the motor's going to have to come out.
Go ahead and order the Raceware Headstud and hardware kit. Might as well order the Raceware Rod bolt kit as well. And since you'll be in there, I'm thinking Aasco race valve springs and Ti retainers. And if you are doing rod bolts, how about some 3.4 Mahle P's and C's, and some Carrillo H beam rods. You'll most likely bump up the compression when you switch to the new P's and C's so send the heads out to Cali for twin plugging. Sure am glad to help out a fellow Dorki.
