Found them on Ebay, advertised as a 64cc head. What were they found on originally. I couldn't find them on Mortec. Any help appreciated.

Those are mid-late '70s 267 and 305 heads with 1.72/1.45 valves and 58 cc chambers.

I was afraid of that. No top end flow then, huh?

No anything flow http://www.nastyz28.com/ubb/wink.gif They make strong torque to about 3000-3500 then that is all she wrote.

Thanks Rob. I'll keep looking. You got any decent heads you're willing to part with? I'm just doing a budget build on a 350 since my 72 has spun a bearing. I want to build THAT motor right, but have to get this thing running without breaking the bank.

No, I sure wish I could help you. I have a set of Vortecs I'm gonna put to use and a set of -193 swirl port heads, which kinda suck unless you really work them over good.

My buddy has a set of G1 Trick Flow twisted wedge heads that I know you could get for an awesome price, but he joined the reserves and is gone for his 2 week a year commitment. If you are interested I will certainly let him know! Those are the only heads I know of.

If it is off a 267" motor, it will have 1.72"/1.38" valves!

Absolutely, tell him I'm interested and see what his price is. Thanks again.

I have a set of 882s that need a rebuild and a set of 1971 339s that are ready to bolt on. Both are nothing special but are 1.94s and also have a good used summit cam and lifters. You pay shipping and they are yours. Cam is #1102

The ones on ebay are 1.94/1.5 or 2.02/1.6s with 3 angle valve job so they may flow decent.

Roundy-round guys use them. I have a pair still. At 1.72 valves, the intake measured 160cc. They cut real nice to 1.94 and 2.02 - don't know the flow numbers though. 58-60cc. I think mine measurd 60cc, so 64cc sounds right if chambers have been deshrouded. Exhaust valves on mine measured @ 1.5"
