I have a friend with a small block ford with press in studs and rail [self alighning] rockers.He would like to upgrade to roller rockers but i can't see to find anyone who makes them.Do they exist? Derek.
Same here, Real Happy with them and I made them adjustible by using a set of 5/16" Poly-Locks from Mr Gasket. I believe they are listed for a Pontiac
Yep comp. I think there called magnum roller tipped. They even have them in 1.7 ratio thets what I just used on my last motor.
COMP is the only ones that I know of that make what you are looking for. Come in 1.6 and 1.7 ratios. Not quite as good as a real roller rocker - but excellent for replacing a stock rocker. On the left side in the picture. http://store.summitracing.com/partdetail.asp?part=CCA-1431-16&autoview=sku
you can get the comp brand on ebay for $130 or you can get these for $65 they look tre same as the comp. rockers
those rockers are a joke... they don't work worth a jack... don't waist your money... IMO for a few more dollars go get some cranes or some real roller rockers with real bearings.
'Must be why COMP Cams is one of the top valvetrain component companies in the world. Sure, those rockers are not as good as full roller rockers, but they are better than stock-type stamped steel rockers...
