Heads ported by Jason Short, maybe he'll chime in here on these. I ran these with a CC306, stock shortblock. Best run on bald street tires in the 1/8 was 8.3 at 92.8mph (no traction obviously). They have 4k miles on them over the last 2.5 years, valvesprings have plenty of life in them. Never dyno'd the car, never flowed the heads, but almost 93 mph in the 1/8 in a full weight car says I'm making over 400 rwhp and a BUNCH of midrange to pull that with 3.42 gears.


-full intake/exhaust port and polish
-combustion chamber reworked, unshrouded valves, and polished
-stock valves
-competition valve job
-milled .005"
-918 beehive springs (1.76 installed height)
-Comp Cams guideplates
-guides machined down for better wirelock valve seals
-57cc combustion chambers

LE ported LT1 intake ran for about 500 miles, with the above heads. Ready for your 58mm TB.


Intake Sold

I'll sell both for 1100 shipped to your door

I really would like to keep these heads, but my new shortblock was built for a 67 cc head, and I'm not going to run 13.5:1 on crappy CA pump gas. I have pictures of the intake now, pictures on the heads will take a day or two as they are still on the car.

 

still have the heads...
