Proform stamped rockers?

Good luck with the rockers. I have seen some good and bad. Remember who ever is selling a product theirs is always the best. And who ever has them they are the only way to go. There was a time and a place for those rockers with factory stock base circle cams. I haven't seen one since the 90's with a good performance result. The shafts are the least of your items to choose from. you will need adjustable push rods to set the pre-load if using any cam an lifter choice but original.

Guys will chime in and say they use them and some will get away with using them. depending on if they did not deck the block, cut the heads, change the cam or use any other thickness head gasket than stock.
