Would anybody happen to have, or know where i can find a blueprint for the GT40p heads? I'm milling down the rocker arm bosses to drill out for 7/16 stud mount rocker arms, just curious to know the exact specs. Thanks

Yes, I was looking for the exact distance the holes are supposed to be apart from each other I so when I enlarged the holes and retapped them they would be centered and where they need to be.

yea thats what i was going to do.. i just didn't feel like indicating each hole for all 16 of them, hoping for measurements lol oh well, i can't find them so i guess thats what i'll do. and i already have a set of adjustable guideplates, so that works! Thanks a lot

For the record for anybody who cares, this is what it looks like to have 7/16 stud mount on GT40p heads! i don't know of anyone else who has done it, but i think its pretty cool.
