Are there casting or model numbers on those?

I was able to find some casting information under the valve covers. I could not find any exact number when I had it out when the truck was getting painted. The general casting information just tells me that it is their base S/R head and according to the website they come in two different chamber sizes.
A question though... Regardless of the chamber size (which if I understand you will be important in determining which cam I can successfully run) If these World Products Stock Replacement heads are just as they claim, a decent stock replacement head. Then what can really be expected out of them? Is for example, 400 ft lbs of torque at say 2500 to 3500 rpm realistic? An open question to anyone...
