Im lookin for some new full roller rocker arms for my 305 TPI rebuild and saw these: http://www.hdmaddog.com/Chevrolet-GM...-p3679364.html The details are : PRE-2302High Performance Roller Rockers Procomp Roller Rockers are extruded from 6061 T6 Aluminum. Manufactured with precision hydrostatic extrusion process which produces a uniform structure to eliminate any defects during the extrusion process. Larger needle bearing fulcrum can withstand valve spring loads up to 750 PSI, while the extruded body has a tensile strength over 60,000 PSI. I was wondering if anyone had heard of them before because its hard to find reviews and im kinda sceptical and Im just looking for a good price but if these are junk I may as well spend the extra $80 for good quality Thanks in advance =D

uh, what heads do you have? those are 7/16 studs. if you have stock heads they are 3/8 studs.

7/16" is the big block rocker arm stud size. Not a bad upgrade to consider if the heads already had screw-in studs.

I spent $280 or so on Trick Flow roller rockers. Very nice rocker arms, good valve spring clearance.

$190 for harland sharp roller rokers. they are great.

You could watch ebay too, I've see scorpions & a few other name brands
in the $150 - $250 range, cheaper name brand stuff if you don't mind used.
As for procomps I've heard both good & bad. If your using stock heads you'll need
screw in studs & guide plates, or the more costly self aligning rockers. I'm pretty sure the 89 engines use self aligning rockers don't they. these look interesting

thanks for the reply guys and yeah i knew about the studs there are tons of those and just picked the top link they have the 3/8 studs too

so you think this brand is alright? and ive been watching ebay and everything but its hard to find some in a good price range sometimes =P

Thanks
