I didn't wait for 1 guy to text me back and he had 4 heads for $50 but I had already bought 2 more so I passed on them. The cylinder head shop had 10 pairs sitting on shelf still. Today is finishing valve seat cutting and checking crank before balancing

Jeff,
Which harmonic balancer will you be using?
If you are keeping the OEM harmonic balancer, there are two different styles for the late model engines, a small solid hub and a larger rubber one.
I recommend you do not use the solid hub for racing. Although is small and lighter, it does not dampen the harmonics as well as the larger two piece with rubber. With the block having hollow mains, the dampening of harmonics helps the life of the engine.
If you will not be using an SFI balancer, I recommend the Pioneer Part Number DA-4552
