ok called summit and the tech guy said that they are for a inline head. he also said that he has seen them clear a .600 lift cam, but he then said around .510 lift you might have problems???

what should i do, i would like to get the tfs stage 2 cam, and some AFR 185's. the heads that were on the motor before were stage 3 ported twistedwedge heads and the Anderson B-41 cam.
