Brent,
Pauls question is a good one and a timely one. Let us know what you find out if you used the correct bolts or type of studs on those particular stands?
It also made me wonder if your rocker shafts might have been installed upside down or something too?. Just a thought...
When Tom blueprinted my last seat of heads, he even provided some additional grooving to those particular studs to get even more
oil flow into the rocker assembly.
