12v head & promaxx

[12vanthony]

Where is everyone getting cummins heads from? From what I can tell the only thing out there is promaxx or Hamilton.

PDP and XDP are promaxx, enterprise engine gets theirs from Alabama cinder head who gets theirs from promaxx. Some are more up front about it than others but that seems to be the fact after my research.

I read subpar reviews about promaxx and people saying to go here and there instead but it seems they just did not know what they where buying.

What's everyone's experience with these and if there is an alternative what do you recommend?

Head is getting a full p&p (intake and exhaust) a runner and o-rings.

I was looking into a promaxx for my 24v at the beginning of the year but after I talked to a few people I just ended up gettin a new one from cummins. It came with a 1year warranty Haven't really heard much on the others so that's another reason I went with a oem

If your wanting a full ported 12v head why not get a Hamilton head?
