Well, I'm getting things buttoned up on the 383 but today I noticed I have a little coolant leaking from the back corner of the passenger side head. I dont think its the header studs- it looks like its coming out from b/w the block and head. I guess I need to re-torque the heads or should I just pull it and try to see what the hell is going on there. Any thoughts? I used the MP steel shim gaskets and torqued the heads to 85 lb ft.

I have the same problem on my SB. When the car warms up it stops. I was told it was that pesky rear stud (I hope it is).
 
try retorqing them mite work but on the steel shem I always put a little silicone around the water holes.or paint them with silver paint..
 
I retorqued the ones I could get to but the pass side header needs to come off to get to the bottom bolts. I think I just need to take both heads off and go with some composite gaskets instead of the shims. I guess it would be a good time to shave the heads to true them up...
 
Well, I think its fixed. I came home early from work on friday and tore the pass side head off. I found a little bit of the old gasket material still on the head around the water passage near the intake mounting surface. Scraped everything with a razor and cleaned with brake cleaner, sprayed new steel gasket with 2 coats of copper paint and torqued her back down. So far no leaks. I fell like a dumb *** for not noticing the gasket crap the first time! Now, if I can get my timing right she should be breathing through open headers tomorrow morning. My neighbors are going to love me!!
