Thanks Floyd, I have never done this before but that doesn't mean I won't try. After all, everything we do in life we have never done the first time we do it and look where we are today. (of course we get a lot of bumps along the way).

What are the pitfalls of replacing the studs with the heads still mounted? I was thinking that as long as I keep all the shaving off the head (practice good FME) that I should be OK. There appears to be enough room even with the springs still installed. I am a very good "Handyman" but of course not an expert mechanic.

My best bet would probably be to get a better set of heads anyway. Right now they are 1968 #15 (small valve) and am looking to install some 6X-4 (maybe). A head changout is a lot easier I know, except for that darn bolt by the AC box!! Any suggestions on best course of action to get that bolt torqued properly?

Thanks for your insight!
