Have no fear me lad, there are people here who know these things from past experience.

My two bits worth is that if you can raise the cash, have it done professionally. You will also need to have the block magnafluxed, as these flatheads are notrious for cracks, which you want fixed BEFORE you find out the hard way. Check it out in your local area... there are some engine places here and there who know these motors; call around and ask specifically whether they have anyone on the floor with practical experience with them.

Others will chime in later, I'm sure. A lot of Ford owners/restorers here.
