I picked up a bare set of aluminum heads today, only have valve guides and seats installed. One of them is ported to the max, the other virgin. They have holes for regular valve covers and center bolt valve covers. They have seats for 2.02" and 1.60" valves. The burn chamber is heart shaped. There are no brands stamped anywhere. On the outside right under the valve cover lip they each have a sequence engraved: PC 3003-0712-0851 and PC 3003-0714-0858. Also on the raw part next to the machined intake ports side, one has the numbers 712 18S, the other 712 21.
I have a feeling they are Edelbrock heads but not sure. I could call Edelbrock on Monday and see if the PC sequences are some kind of serial numbers. Any help here is greatly appreciated. Jens |

If they are Pro Comp I know the guy that casts them and I know what they are modeled after - similar heads to my Canfields as well. Been so long since I looked at a set I can't say for certain they are PCs but those pix look very much like what I remember and much like my Canfields.
You can make 500HP on a 350 with those heads if they are ported correctly. Just be careful to check the valvetrain geometry on them when they are installed - you will have to get the right pushrod length. |
