Ok, my top end is up for sale. It's still at the engine shop being cleaned, but everything checks out and is good to go.

Heads: Joe Prince Racing ported early LT1 castings. 52cc Combustion Chambers, 175CC Intake Runners. Flow for .100, .200, .300, .400, .500, .550, .600 is as follows: 72/69, 125/110, 182/139, 224/158, 242/168, 255/188, 260/203, 260/203. Exhaust was flowed WITHOUT a pipe, and the flowing was done on an independent flow bench. Heads have approx 500 miles on a fresh competition valve job also, with approx 1000K miles total on them since porting. Heads have XE Components 618 springs set up at 1.8" with less than 500 miles. Also have Manley Race-Flo 2.00/1.56 valves. Everything is installed, ready to go.

Manifold: Powdercoated red w/polished fins 92-93 intake manifold. Runners port matched to heads by Joe Prince and opened up for 58MM tb. Manifold was cut to match heads (due to milling of heads) by Golen Engine Service two times to ensure proper sealing and no oil leaks at the runners.

Cam: Custom Joe Overton grind for these heads. Will PM specs to serious buyers.

Of note: These heads are good. They made 375/363 to the wheels with a 224/230 XE cam through the full exhaust (mids) WITH a cat on the car. According to Joe O, the cam being sold with this setup should peak at 6700ish and make 410-420 RWHP in a properly running and tuned car with all bolt on's.

Looking for $1700 plus shipping. At this time I WILL NOT seperate parts out as everything in this package is meant to work together.
