so yeah im debating on either a set of TFS 215s or the PRC 5.3 heads, i know with the trickflows ill have to mill for the cam but how much more am i getting out of them? and i know the PRC heads are a good deal for the price they are and the power they can put out with a MS3. As far as the set up goes

MS3 cam, PRC dual springs, ported ls6 oil pump, ls2 timing chain. with this and the mods in my sig i put down 380 rwhp at the wheels through a A4 but now i have a ported 92 fast on the way but just wanna know what heads will work best for my set up. money is always an issue but are the trickflows worth saving for? thanks.

The PRC 215 head can ship with about a 60cc chamber & still maintain good p/v clearance. Becareful with the other cylinder heads, just because a head has a twisted over valve angle doesn't mean they can clear larger camshafts after milling!

The PRC 215 was built specifically to clear larger camshafts like the MS4 with a smaller chamber.
