i just called them today to ask about porting my stock heads and he was like its a waste of time then i asked about a 4v swap and he was like thats your best bet then he was like acually we have a set of 4v heads 03 cobra timing chains and 03 cobra timing cover well sell you it for 1500
Does that 1500 include gaskets, bolts, intake manifold, exhaust manifolds, throttle/cruise cablesetc? How complete is the kit? It will drop your compression ratio a bit which would be great for boost (though the rods/pistons are still an issue), dunno about with your nitrous though...
