Is there anyway of finding out what year the heads are on my engine without ripping the heads off? Right now one of the valve covers are off, and I noticed 3H8 and ofcourse 302, I also found numbers runing in a circle, but couldn't read them...
Hey cmpcpro, That head date is August 8, 1973 or 1983.
3 - 1973 or 83
H - August
8 - day (8th).
If you look on the block near the distributor, there should be a small flat area with a similar format date...that is the date that the engine was actually put together. Of course, the heads may have been changed!
