AFR LT4 heads
Selling these heads for pretty cheap since they have a repair.
AFR LT4 heads ported by Jordon Musser. Some may recall that Jordon ported his old AFR's on his solid roller 401ci LT1 that ran 10.8@130 on motor. These heads have the same portwork as the heads he did for his car.
The heads are currently at around 214cc intake runners. They are large chamber heads (69cc) designed to lower compression ratios into boost-friendly range. Or, you can mill them down for NA. Valves are 2.055/1.60". No valvesprings....EDIT: I have a complete set of 16 Comp Cams 977 valvesprings with around 4k miles on them that I will include. You will only need to buy the retainers and locks.
The heads had a small pinhole in one of the exhaust ports. They were professionally welded and then pressure tested to 80psi and do not leak. I just had a fresh valvejob done on them as well. They are clean and ready to assemble, mill, or whatever. One of the headbolt holes was sleeved as well.
To sum it up, these heads are not as "pretty" as a CNC ported AFR, and have a weld repair. But, the porting was done by someone that has numerous great results, and the price is very reasonable.
SOLD

Re: AFR LT4 heads
I have a complete set of Comp Cams 977 valvesprings w/4k miles that I am now going to include with the heads. The only thing you will need to buy is the retainers and locks.
Price is $650 plus shipping and includes the heads, fresh valvejob, clean heads ready to assemble (or mill to desired compression ratio), Complete set of intake and exhaust valves, and a full set of Comp Cams 977 valvesprings. That's a killer deal
