Would a head gasket get you close enough? What is your project? Could be interesting! If you have not done so already you might try posting on the W7 W8 W9 pages on Facebook.

The project is a set of victor heads. They have tapped holes from the deck side and on center. I will post more info on the build soon. It is a Ritter block with victor heads. This will be a twin turbo build.

You have to fill in the hole in the deck as the new hole is only half into the 7/16 hole from them and it will push you mill bit off center.

Yep, on the r3 18 bolt patterns,the smaller upper studs are not central to the bore..but i think they are on the bottom row however. I cant remember
