Matt,

I came across a set of heads with PN# of p4150021 what the heck are these??.. They look like PN#p5007428 (p7 heads) in the Mopar Performance catalog.

Jim,

Unfortunately that number doesn't seem to come up in any of my listings or with any of my sources. Is there any way you can take some pix and send them to me so I can dig a little further? Maybe a shot of the combustion chamber, one of the rocker arm area, and intake and exhaust port photos.
