Do any of you guys know the casting # that you guys are using for your d/p heads. I came across a clean set of uncut d/p heads and didn't know if they would be good for any of you guys. Would prefer to get them to someone who could use them before just listing on The Samba, etc.

I need some but am not sure on what castings... I will see what I can do on this and maybe take them off your hands.

What's up Jeff. Do you get an email alert when I post in the Class 9 forum or what?

Thanks Frank. Read the rulebook a little. It says Brazilian 040 or stock OEM. These are German heads and the casting is #311 101 375D. Here's a couple pictures as well.

Don't know if these meet the rules or not

I think the biggest thing if they are 040's is to CC the heads to make sure they will pass.

It takes a lot of porting to make a stock set of 311 heads flow as well as a set of stock 040 heads. Since porting is illegal and 040's are legal - no brainer.

Good info. Thanks. Clearly I don't know heads as well as you guys do.
