Hi guys,
I've had no luck trying to find out some info on the heads other than valve sizes. The head is listed as a "motor home" head but I can't find out anything more on it...like chamber volume or what the the compression ratio might be on an undecked 3698830-440-6 block that has been rebored .030 over.

Anyone know the flow numbers, port sizes, or anything at all on this head??? I'm trying to determine what kind of horsepower they may generate with a mopar performance six pack cam (268/.450 int,[228@.050]; 284/.458 exh).  

sorry, posted it a bit early...
Intake is stock (for now...thinking of Eddy Performer); carb is Thunder AVS 800cfm, 727 tranny, 323 rear end.

Putting headers on it this weekend.

Any help would be appreciated.  From here I have to figure out if its worth changing heads to something like Edelbrock or 440Source Stealth heads and what the upgrade in horsepower might be like (versus the cash to put'em in!)  

anyone have any ideas on this?  

Don't bother with the performer on a big block, it's just an aluminum version of a stock piece.
Get the rpm.

The 213 heads are alright, motor home heads I think.
Ported 906 or not ported 906 heads have more potential.IMO
The stealth heads are the way if your considering an upgrade.
