SM Head Modifications on a budget

PRH said

I understand the goal is 280+ by employing a process that minimizes any more rework of the SSR than necessary.
My thinking at this point is……..you’re going to have to uncover a fairly significant problem area that yields healthy gains………that don’t keep the port from being so dependent on a better SSR.
As I see it at this point of the development………it’s still all about the SSR.

It’s very reminiscent of my earlier exploits with 906 heads.

This whole exercise is to help guys out that aren’t afraid of getting dirty and don’t have enough money on hand to send them to you, Brian, myself, or any other head porters out there. I could never take the time to test these relatively simple mods and almost anyone could do at home and gain 20-50 horsepower. He’s willing to do these tests but like you said to hit the upper side of our target he’s going to have to get rid of the bolt bulge and I’m sure lower the shortside and some shaping. I too like you did this 40 plus years ago to gain what we could on J, X, 906, and any other junk head that we had to use back then.
