Default Ugh, Pulled threads

While reassembling the rocker box on the front head after gasket replacement, the threads for one of the rocker support plate bolts pulled out of the head. This happened just past contact. Didn't even come close to torque (18-20 ft/lbs). While I could fix this myself, the 98" kit from Hillside has 30,000 miles on it, so if I'm gonna go that deep, I may as well do a refresh and have the heads done as well.
Just got off the phone with Scott at Hillside. They'll do a hone and ring job and a Stage 1 head job to match my cams.
Mixed blessing, I suppose.

I HATE the feeling of tightening up a bolt and the threads go away............
But doing a refresh never hurts!

I can sure sympathize on that ill stomach feeling when it happens.

Sounds like the silver lining plan is a good one

Got it all apart and I'm living right. Of course one of the wrist pin circlips fell into the case. I managed to fish it out on the first try.
