Get Your Motor Running with a Pair of Chevy NASCAR Heads
Thousands of dollars went into making these Chevrolet R07 cylinder heads ready for competition, all yours for $3,500.
“They’ve got about $10,000 in machine work and parts and labor, over $1500 in the valve train alone,” says ChevroletForum member MrBlah of the Chevrolet R07 aluminum cylinder heads he’s putting up for sale. The heads, which were built for NASCAR competition, were acquired in a trade.
Here’s what these special Chevy heads have going for them, per the seller:
Titanium Intake valves : 2.180 head x 5.980 long x 6mm stem weighs 73 grams
Titanium Exhaust valves : 1.6325 head x 5.735 long x 7 mm stem weighs 63 grams
These come with valve seat locators, polished PSI valve springs & mini top lock titanium retainers.
Approx Spring Rates: 200 lbs @ 2.00 in, 575 lbs @ 1.250 in
They have been fully CNC machined and ported, Intake port: 1.730″ x 1.985″
They flow upwards of 375CFM and can handle up to right around 12,000rpm.
The Colorado-based seller is asking $3,500 for the heads, which look ready to hit the track atop a Chevy-engined dirt tracker. The seller adds that he would “prefer a local trade or sale around the Denver area.”
