Yes porting and polishing increases the flow of air to the engine but this only makes it easier for the engine to run faster it doesn't allow it to get there faster. I don't know how familiar you are with engines, but "Porting the head" means modify the cylinder head so that more air will flow thru them and into the cylinder. Cylinder Head & Intake Packages. I buy core cylinder heads in any condition and for any TDI, TD or NA style diesel head, exchange or without exchange.
