I bought a wilmo manifold from a club member and send it to be blasted and ceramic coated and polished. What I need is to know is what would be the correct size studs to mount it on the engine block. I want to get the right size so I don't have to cut the studs down and then those surfaces get rusty. This manifold doesn't use the original clamps like some I have seen. Also looked at some of the prevoius threads but didn't get a solid answer on correct length and size studs. If anyone knows thanks for the information in advance. Tim
Should have said Wilmo manifold. Thanks to auto correct. Tim
Take some stock Ford studs, add threads and cut to desired length.
See Royce's advice in this thread:
Don't know why cutting them has anything to do with rust. Stock studs are going to get rusty regardless if you cut them or not.

Put it on without the gasket, see how long they need to be. I think the 26/27 studs were shorter, if they are too short get a set of the 25 and earlier studs. Add a washer under the brass nut or two. I would use brass nuts with washers under them anyway. Paint the ends of the studs and put anti-seize on the threads. Did you check for flatness before having it coated?
Mark, I did take it and have check to make sure it was straight but it was still near perfect. It seems like it will be easy to take off and on with studs compared to the stock manifolds. Tim
