i understand, but you wont see the gains as you would on a B series head.

put it this way, THE TRICKEST B SERIES you can BUY flows 300- 315CFMs.

a Stock K series head flows 300CFMs with ease. Call RLZ and ask to speak to Brad, he will tell you some stuff or search for it on HT

You still have a 2.0L, it can only breath so well for its Disp. VE can only be so much.
