Default First Pics PRC 220cc As Cast Cathedral Heads INSIDE!!

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 are built for 3.9-4" bore applications & are 62cc before milling.

Thought of a price on these yet? Tfs as cast 220's are 1679 so priced accordingly OR CHEAPER im sure these heads would sell nicely.

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!!

Will they work better on a 3.90 bore strikers than your 2.5 LS6 heads?

They look very good and I am sure will perform just as well. Do you have any closeups of the combustion chamber?

Sounds like this is the head for me! Now someone just needs to talk my wife into letting me spend some more money on the T/A!

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!
