I just pulled them off a 427ci car we are doing some work to.Should have head specifics tomorrow or weekend.So far I know they have dual springs and bigger valves(will measure )

Just throwing this out there for some thought.Will come up with a price after inspection,cc'ing,ect.

Also a 230/240 Cam.Have to check the cam vin to get the rest of the specs.

Also,3 year old Tella Terra rockers.Probly 800 miles on them.Look new.

 

how much for the heads;; an how big are the runners.. an;
who;s valves are they.. interest it..

 

I'll bring the heads home tomorrow night and during the weekend I'll CC everything and take valve measurements.

 

are these coming off a pewter ws6 by any chance?

 

Probably a NMB Firehawk...

 

They are coming off a 2000 NBM convertable Z28 that has a Procharged 427ci in it.

 

Head specs.
4.060 bore
62cc chamber
Ferrara 2.10 intake/1.60 exhaust valves
245cc intake

They will work on 402ci +. Will take $800+ shipping.

I have no flow #'s.On car for less than 1k miles

 

U might have one of Joe's decent ported heads there don
Wonder what they flow,bet they would work good on a larger engine...

What did the car dyno with this setup?
