Hope you used the copper antisieze and not the gray stuff. The copper works better in marine!

Put a 741 or 651 cam in it and be done with it. Easy on valvetrain and proven results over and over again.

Your exhaust sucks too.

Ya I know, and it seems I'm standing on "that side" of the fence now, sucks to see this happen but I guess it is what it is, not fun to be kicked when down after so much effort, most guys would have tossed the towel long ago... I won't give up and gonna see what round 3 does... If I fail I will address it then.

I think I'm gonna rely on my plan I had from the beginning of this and go with it. That's just how it is now

Otherwise that one that howards had that was mentioned about 50 pages ago. Nothing wild and around 243/249,253-640/640. Think MT posted an article on it.

I used the two part system. I think it's made by JB Weld.

Tim, for what it's worth you saved me a chit ton of money and headache with your saga. Even through the cat clawing in this thread it's a wealth of information.
