Ive been takign apart and cleaning up eveyrhting on my 71 fastback, eveythign from the trans/engine/ engine bay/rear end/suspension. And adding new/performance parts wherever i can. Ive noticed by part #'s that this car was mismatched with parts ALL over, a 9 inch from this... a locker from this year, a diff shifter from this, a trans from another year. So the engine was rebuilt andi took the heads off to redo the headgaskets a while back, i took pictures of the heads, cleaned them up, did a port job like in this: http://www.sa-motorsports.com/diyport.aspxthen threw the engine back together with more performance parts. At the time, i just got the car and didnt think much of heads. now its been a little later and i was lookign for something new/improved but i was curious if anyone can tell me anything about the heads that are on there now, just from pictures, Do they look milled? surfaced? Stock size valves? I never measured them when they were out because the heads were the last thing on my mind because i was unsure if i was going to use them or not. The casting cide is D0OE, so thats from a 1970 torino 302? and its in my 71 mustang... more mismatched? do these look like stock valves?



The reson i ask, if these heads were "done( with larger valves)" before i put them on what would be the point of putting on some mild ported gt40p's -Jon

 

They look pretty much stock to me. You could measure the valves but you will find they are most likely stockers. Its tough to tell if they have been decked without measuring them.

The point of going to GT40 heads is better ports and much more efficient chambers. Pain and simple a much better head..

 

Yours look stock to me. Here is a pic of my heads, they have oversized valves in them. 1.94 intake and 1.60 exhaust.

Look stock, and valve sticking up indicates the valve has not been ground. Mill marks would not be visible on a picture but if you look close around the bolt holes, wear no gasket is, if they have been milled you should see marks.
