Finally the decision has been made.

On a budget what I found was the comp 926 singles using the rest of the stock guides, retainers and locks, is "good enuf" for a pretty decent cam. All bets are off if you are going around over 6k rpms a bunch. But for a simple street motor I am going to run a howards .502/.525 on 926 springs with hughes 1.5 rockers. I think that should do just fine.
