Will they work for my setup??? TFS Heads, b-31 cam, and 1.6 RR on there right now. I might the most power out this bitch N/A. Will they clear the Trickflow Valve Covers?? And what are the power gains?? Will i need to change my springs?
Call AFM and see what they think. I know the B-31 is the same as the B-21 cam except for the difference in rocker ratio. The lift is .544" I/E. So, if you went with 1.7:1 rockers with the B-31 your looking at .578". That's a lot of lift.
