engineering machine shop,using a milling machine.measure the gap and gasket,as they have to machine both sides.they will have to work out how much to take off.

I wonder which was machined incorrect to start with?
Heads, Block or manifold?

Even decking heads/block, the angle doesn't change.

the angle doesnt change,but the size across the v does,if you decked the block,shaved heads ,the manifold wont hit the gasket.so you have a choice to machine heads or intake to make it fit,intake is softer.when i decked my v6 by 3mm each bank,i had to take 8 thou off each side of the intake,theres more time in setting it up dead square,than cutting.
