Heads or not...?
I have 136k miles on my LT1. I contacted AFR last year and they suggested I do a rebuild on the lower end before I got the heads, the gentlemen told me there could be possible leak down on compression....anyone else have high mileage engines that have had aftermarket heads put on? If so any problems? Anything else I should be concerned with in regards to putting new heads on an old engine? Thanks in advance.

Sometimes, you get away with it, and sometimes not. Even a budget re-ring job would be wise. If the bores only have .003 or.004 of taper, hone and rings may be all you need. (other than bearings, gaskets, etc)

I would advise that if you are going to do a re-ring job you also change out the wrist pins and bearings.New rings would be tighter and the play in the other components that I mentioned could cause some knocking(It won`t be opportunity).Just my opinion.

About how much do you think all this preventative maitenance would cost? Just a guestimate would be fine. I'm not the best with a wrench so I would prolly contract it out. Any ideas?

I posted the same question a few weeks ago and every one said the complete opposite. People said it should be fine if it was well taken care of, and you don't spin it to high. There were several that posted and had done heads/cam on high milage LT1 and had no problems. I guess it is a gamble, but if I was going to go to all the trouble to work on the short block, I would get a stroker.
