Who makes upgraded rocker pins and clips for this head? Thanks
when these engines were first being release a few reports were on the old forums of people breaking the pins.. I made some better with snap rings but no need for them.. I believe the reason there pins broke is because the rocker geometry was off.. I turn my 8k+ every weekend on stock rockers, pushrods, pins and c clips..
I guess I am behind times....who puts a hemi head out? which engine?
What's the heaviest springs has anyone run on these? I'm gonna be runnin nr 307 with 37# springs
