Guys we've been working for about 5 months tweaking the all new PRC 220cc as cast runner program. We hope to have them available in about 90 days!
Each set will feature the 6 bolt PRC castings, Manley valves, PRC Spring kit, and will have cnc chambers & cnc shaped guides for optimal flow!
Testing has show 320cfm+ capabilities out of the as cast port!!
Enjoy

They will target a similar pricing range, but are designed to out perform ANY as cast cylinder head on the market by a pretty nice margin!!

Im unsure on exact weight, but our PRC aftermarket castings come standard with 13 degree valve angles. We do offer a powdered metal guide option if the customer requests it. I will also add that intake port alignment with the FAST is very nice!
