Engine Combo Questions

That’s some good info! the 4" Stroke would make a nice square motor. I would really like to go Alu. head for weight and for a modern combustion chamber plus its much easier to port or clean up for me (used to working with it). Which brings up another question about porting how rough should the ports be for use with a carb I have heard in theory that a carb'd engine want a rougher port? But I don’t have any empirical evidence to back this up.
