A friend has a set of unfinished cylinder heads. P4532795, what are they, he doesn't know?

for the most part with any Mopar stuff.... if that's a number cast in the head it might just be that. Most of the time the number on the box or paperwork would actually reference as to "what it is".

No box or paperwork with them. The numbers are stamped on the end of the heads. They are raw unfinished castings.

guess I was "assuming" iron.... are they aluminum? there was a run of "commando" aluminum heads back in the day. We have some MP iron heads on our 360, but no number on the ends of the castings.

Yep aluminum, raw castings, nothing drilled, no bolt holes, guides, or seats.

I saved a metric ____-ton of information when I left MP, including every historic casting chart I could get my hands on. Filed away in the basement. Want me to check when I get home?

(holler at me on social media, I check in here maybe once a week)

It's been suggested in the past to make a
book out of that info and sell the book

That would be great Rich

Cool, that will help me remember.

Thanks for the info!

QuickD... so your “friend” must have gone to March Meet a couple years ago .

Those look like an excellent candidate for “how to spend 3-4 times on cylinder heads than what they’re worth”.

Well.... we are mopar guys Dwayne!


I thought saw em in two and have some really cool wheel chocks....

Unless someone had a cnc program for that casting, to do all the normal machining on them(all the bolt holes, rocker stands, guide and seat bores, vc rail, basic milling), and wouldn’t charge a fortune for that...... and there were an affordable option for cnc porting as well...... if those two conditions can’t be met(along with someone just having to have them).... then, “IMO”...... they are only worth what they weigh for scrap.

Or, like you say....... conversational wheel cocks.

Id say just the opposite. I wish I could buy parts in that condition. Nothing removed from any areas that the oem dictates need to be removed. Pushrod pinch, valve angles, seat angles, chamber shape, rocker stand placement, etc...

Place an add in the want ad section, time to tool up. Since your gonna be bug deep in these heads you shouldnt mind a modest buy in for the castings and people got them.

So what ya gonna put them on?

I stumbled across this post looking for info on another “P” head... when I was at March Meet 2 years ago these raw casting were in the swap area and I know the seller was from MN. I’m sure they’re the same ones the OP was talking about. While basically worthless, it’d be interesting to know their story....

I should have been more clear... not these specific heads, but any head / block I would want. The best example I could come up with would be the B engine stage 6. The raw casting has so much potential. They ruined them with the pushrod holes, the spring seat location, the rocker stand positions etc...
Then another thing that comes to mind is the Original ritter block. Let me buy a casting. I’ll put the machined areas where I want them, not worrying about errors or unneeded Machine operations. Seems to me that the wait and errors of machining are the hurdles that keep blocks from making it to market. I realize that I am in a small minority of buyers, but why not offer raw castings as an option. Heck, you could even use it as an advertisement advantage... “Blocks starting at $1500! Available now!“
