Only the exhaust side to fix the excessive wear which showed on some of the exhaust lobe flanks; there is a different cam in his engine.
That should work well for your application.
IF he still has it.

I would bet that carb won't be enough, Quick Fuel 1450 is seeming to be a good choice on the bigger engines that Phillip has been doing lately. That thing will be a beast in that buggy when you get it going. Hold on for dear life Shocked

In the directions A.T. sends with the heads, he suggests a 2.500" intake and a 1.840" exhaust. Kind of curious why you chose the 2.480" and the 1.880" sizes?
