Hey motor experts,

I went to my builder today and he showed me the progress on my motor which is just about done (all boring, porting, etc is done, he just needs to assemble it). He showed me the porting on the head and he even did the intake manifold (the aluminum part inside if the rubber. He made sure that everything now "matches" without any lips , differences in diameter where the manifold meets the head and of course the work to the ports themselves. Do most machinists do work to the intake manifold also like he did? It sure looked good...

That is what a port job is, they make everything flush, for the smoother flow, and yes it includes the intake. You suck in more air so you can push out more air, or else you exhaust will be trying to blow out out more air than the intake is bringing in. It makes it all work together.:D
