Default Re: Flathead project

3.06? sounds like a 221 cu in motor at 3-1/16" on a standard bore. Plenty more meat in that one if you want to go bigger. Early days yet, most important thing to be looking for is cracks. Check all around the head faces and around the bottom of the block on the sump face and inside and outside the block around the sump face.

Can't recommend anything re extra support as I can't guarantee what will work. (But anything is better than nothing)
