Sean B - Yes, I am 100% sure it's a Poly...2 and only 2 valve cover
bolts w/ a 'scalloped' bottom edge to the covers. Don't feel bad about
asking!

Doug - Will the casting date be stamped in the drivers front corner as
well as the assy date? Or is the casting date cast into the side of
the block like LA motors. I'll pull the numbers when I get home
tonight and post them. I have my fender tag and build sheet and have
decoded the car. Built May 19th, 1965.
