Greg, newer heads do have different drain holes
By Geoff McNew - 10/15/2003 9:51:21 PM; IP 66.52.140.29
Edelbrock says they have indeed changed the oil drain holes from the type in your photo to the type I have with the head bolt going thru the passage like a stock head. The gaskets don't interfere, but, unfortunately they left the "upstream" portion of the drain holes tinee weenie soda straw diameter. So the friggin oil still wells up. Edelbrock recommended opening up the hole....I recommended THEY start doing so...make sense? Oh, they say they also changed the OD of the guides and thus the newer heads have a different size seal.

This thread, so far...
