Cylinder heads are a little more tricky as there are several different varieties that Ford had...Of course with that said, they might (might) be the D1ZE-DA CJ heads if the original builder stuck with the matching set. The date codes are within 30 days of each other which makes me believe that they are the CJ heads, but without checking the actual casting numbers I am not 100% sure right now. Most likely the 74CC 4V heads with an intake valve size of 1.71" and an exhaust port measuring 2.00"X1.74" . Really need the casting numbers off the heads so we can determine exactly what they are though....All in all a nice platform to build up a killer engine unless of course that has already been done....Any chance that the seller has dyno numbers on it? perhaps before you pull the motor you might want to speak with Sal about some chassis dyno time to see what the engine is putting out to the rear wheels, you can then decide if it's enough for your needs and go from there.........

Thanks, Bill. I can't seem to find any numbers on the heads other than these.
Where on the head will I find these numbers? I was surprised with the block number - as an old Chevy guy, the numbers there tell you exactly what the block is and what it came from. No such thing on Ford's huh? I wanted to stop by Sal's, but after I get the car back together. I'm going to run the Cleveland anyway, at lease for a while. I want to stop by Sal's when it's done and have him dyno tune the finished product. That OK with you, Sal?
I doubt the heads are 4V, as they have a big 2 in the back corner just past the valve cover surface. That would make them 2V heads, no? Ah, no sence guessing - I'l have the motor out and dissasembled hopefull by the end of the week, and we'll all see what the deal is. Thanks, Bill!
