SM Head Modifications on a budget

But the title of the post is 'on a budget'. Still trying to convince my wife that she really wants a dyno.

Ya but 90% of the guys are going to get their valves backcut by the guy checking out their heads and doing the competition valve job. You would be dangerous with a dyno. Lol. Wow I typed this out hours ago and forgot to push post. Damn phone calls.
