Well you could put them on a street motor but I dont think people bother.Really there just for high rpm, high lift racing cam engines.

are roller rockers really not for street? or is it jsut a bunch of $$ for a street motor?

seems like the less drag on the motor would be good.

Roller rockers are about $750 cam $150+ Springs $120.

My guess is that more than you want to spend.

I need to know part numbers and prices for the stuff so i can get a fair idea of what its gunna cost

If your getting a regrind get the roller rockers as well cos they put less strain on your cam therefore solving issues with reground cams wearing quickly.

Is this for a race engine ?

If it just for the street I dont think you'd need roller rockers or racing pistons.

Hey guys.
Im Looking at rebuilding my A15. I need some advice on how to go about getting some more HP without going overboard. I can get my cam reground, I would like some good specs to grind to. Maybe roller rockers. I hear that yella terra make them but I cant find the p/n in the book. What pistons are best without buying forged or racing ones. Which valves should I use? Also who makes double valve springs?? (part numbers and suppliers would be great I work in an auto parts store Australia)
