I have a set of LT1 heads that are CNC ported that I would like to sell.
I’m first putting this up locally before I put them in the For Sale section so is there anyone interested locally in a set of CNC ported LT1 heads?

Here is a little information on the heads;

The heads are CNC ported and have 2.00/1.56 Manley stainless steel valves, toped off with Crane’s springs and retainers kit 10308-1 with dual coil springs. The heads also have guide plates installed.

Well here are the flow numbers on the heads.
Intake Exhaust
.100 61.90 43.30
.200 125.70 101.70
.300 183.20 145.50
.400 224.80 177.80
.500 250.90 202.90
.600 260.00 218.70
.700 260.00 224.50


The Heads were flowed at SD Performance using a Superflow 600 flowbench, if you are interested, would like more info or would like to see a copy of the flow sheet send me an E-mail or PM and I’ll try to get back to you ASAP.

EDIT: Price Reduced

Now asking $2000 cdn. with an LT1 intake that has the throttle body area ported to 58mm.

 

how much you lookin for?

 

About $2200, but I willing to work on the price if someone local is intrested.

 

Are these just stock castings ported out?

 

They are the head that CNC Cylinder Heads, Inc. based in Florida uses to for their CNC porting. Basically they are a LT1 casting that that has more material in it so that they can CNC the heads to what ever profile is loaded onto the CNC machine, without worrying that CNC machine will cut into the oil or cooling passages in the head.
