On my stock block and W-2s I had BB roller rockers on it(they were packaged as SB rockers) but
I had issues with them from the get go till I started measuring them.. The portion that was on the
valve was long and they needed caps.. at about 7000rpm they would kick out the caps.. I had
a pile of cap in the valley.. glad I screened it.. soon after I got SB ones then things were fine and
it would rev like it should have and didnt need caps.. I learned alot
