Thread: Partout & Demod - $5 SALE!!!

What you have are some home ported or shop ported heads that hogged out the D shaped exhaust ports.
Hope this helps, glws.

SnowFlake - I spent a good bit of time today trying to find out for sure, and it turns out you're absolutely right. I'm now 99.9% sure these are NOT ZZP heads, but I do still believe they were professionally done. Unfortunately, I have no receipts or anything to prove that, but I'll try to get some better pics up soon.

As a result, I have edited this post and reduced the price by $150. on the heads. I think $250. has to be a pretty good deal for someone given the amount it would cost build a pair like these.

I apologize if I misrepresented the heads or misled anybody.

Thank you SO much for the helpful input. You probably saved me a big headache.....not to mention the shipping I would have had to pay when a disappointed buyer wanted his money back! I'm always impressed by the amount of knowledge & experience on this forum.
