Some good suggestions here. The only thing I'm concerned with is getting to that last head bolt and swinging the torque wrench 360 degrees without any increase in torque. I'm sure we all know that burning sensation. If its only the older engines that dont have inserts than I should be fine since I have a 560. I also dident realize there were bolts at an angle unless you are talking about intake manifold to head. But as far as jigging is concerned for that I do have a Bridgport Milling Machine. My intent for the head bolts was to make a jig block out of a pice of steel with a hole on each end, one as a drill guide and the other as a tap guide. I had no intention of doing manifold holes unless necessary.

Thanks
