I have a set of pro-comp roller rockers on my sbc and uh.... my advice.... go with comp cams. Pro-comp is just cheap foreign made parts and really not worth the money. After 3 weeks of being on my truck the poly lock SOMEHOW backed off n i heard the motor go to tickin and luckily i did because 3 came off. I dont see how it came off like that but i guess anything can happen.. and YES im sure the lock bolts were tight.
