have you ever considered the GMPP CNC LS3 heads? They are $595.99 assembled each. Flow wise, they beat the TF down low, but the TF beats it up high. Bang for your buck, I think the GMPP CNC LS3 heads are hard to beat.

GMPP CNC LS3 heads? Port size 279cc! very large!.......Also talked to Jason you will have to change rocker-arm pedestal to change over to TSP ls3 style heads from factory L92..I'm using T&D shaft mounted rockers..T&d stated that you could shimmy it....Also Jason stated that the as cast versions of the 255's will be out around next month for around 1500 bucks.

Anymore comparisons on the PRC 260's/Mast medium bore/ TFS 255's? Trying to decide which ones would be best.

I went with the TFS 255's aswell but will be cnc'd by TEA. By the research I have donr, the TFS has a smaller intake and exhaust port then PRC and the MAST head and still outflows both of them. You also cant beat the reputation of a trickflow.

I still haven't seen the flow numbers on those heads? Have them as well as pricing?

Great thread on the heads. Got mine from Martin for 2590 with titanium rwtainers and PAC Springs. They also come with billet pedestals for ls3 rockers
