Aluminum heads/intake

[DHall]

Trying to identify the type of aluminum heads we have. Part no. P4532134. Thought we were getting Stage VI. Have M1 manifold. Trying to find a manifold that will work with these heads.

Are those stage VI heads? On what block?
On a B block, use an RB intake.
On a RB block, use the spacers in the MoPar Performance Catolog.

It's an RB block. We have the spacers. We bought the heads through another guy. They are supposed to be Stage VI, but... We are having problems getting the manifold (M1) to work fit, even with the spacers. Were looking into what to do next (the guy we got these thru is pretty much into Chevy's and trying to break into Mopars. The part number we found stamped on the heads was P4532134. We can't find that part number anywhere and it doesn't match up with the Stage VI heads in the catolog. We got to thinking that they might not be Stage VIs after all.

Thanks for any help you can give me on this.

I would give Mopar Tech a call and ask what that part # is. Here is a link to their contact info.

well if they are used heads they might have ben milled, how much, who knows. if that is the case then you might have an alignment problems, has the block been cut?????

there is a formula for thous. cut from head & block for how much to cut intake to fit. the next problem, how much has been cut to make the formula work and finding a shop who knows the formula and will take the time to cut the intake/spacer.

just something to think about
