I have a 79 351w engine 30 over balanced and blue printed with forged pistons a lunati 540 lift flat tapped cam with a set of real hipo 289 heads hogged out pls no laughing ! with crane 1.7 gold pedestal mount roller rockers , weiland stealth intake and a holley 850 dp and bbk 1 5/8 shorties. Engine has been dynoed at 450 and putting out 10 3/4 to1 compression. Will these heads work and What would i need to do to make these heads work?
These heads first off are a stud mount, you would have to do an conversion to make them work if you want to retain the rockers you already have. Other than that you should be fine. Depending on your valve reliefs in the piston you currently have we would recommend to check PTV interference when installing them. That will also come into play with your cam profile as well.
