SM Head Modifications on a budget
Ok just working the common wall for five minutes I gained .030 the length of the pinch. That’s a nice gain and I’m no where done. Just working down some of the bolt bulge look how much short turn area I gained already and I didn’t tube them yet. My thinnest area at the pinch is from .062-.118 so I wouldn’t push that .950 number unless you are tubing everything. But like I said don’t touch the common wall till you have your .950 so you can pick up another.030 like I just did.
