Contact your vendor with your specific combo. I just installed GN1 heads and a roller in mine. I went with a CompCams 218/212, Scorpion 155's,which many will say is too large for the street. I say BS, this thing is awesome with my combo. Will it perform the same for you? Depends on your combo. Jack Cotton can set you straight next week when he returns from his honeymoon.
Good luck
