How did you go with your 3 cyl you were experienting with porting etc, a silly question is there any point in polishing the piston tops and cylinder head chambers?
But any smoothing of the intake ports and exhaust will help the motor breath better and add HP.
The tops of the piston and head will only get carbon as soon as you start running.
Bugger this is what happens when you dont frequent pages, very sorry to hear he passed he was very knowledgable when it come to the chryslers, rip Frank.
