Yeah you are totally right, it's not just the name. Call up any "REAL" aftermarket ls-x shops, and if they aren't trying to sell you a certain brand (cough, cough) the afr and trickflow castings outperform almost every brand and factory ported casting period. Dart and Edlebrock are good "budget" options. Basically no way anyone is going to choose a PRC head over AFR or trickflow at the same price. I would be MORE than happy in the $1300-$1600 range with a single conical spring per pair to give the new PRC casting a chance. Not really sure why PRC/TSP didn't try to develop a ls3/l92/ls7 next gen casting. Seems like the cathedral port aftermarket head sector is loaded with MANY competitive options. Best of luck

Sounds promising.. Wouldnt mind being a test dummie soon. What do you have for a n/a 408 stroker 11-1comp, 650 lift 111 lsa cam, ported fast or ssheet metal threw a m6 with 3.73... Do you have a head out that will alow that setup to push some power, cams a tad bigger that a ms4..

Guys we're working hard to get these things tweaked for final production. I'm testing several sets on cars right now, & we'll try to have a set at the race next month!!

I like that it can fit the MS4 with out flycutting if you wanted to step up to a large cam,but lets say you have your tsp 5.3 stg 2.5 heads and wanted to keep the cam you have..How much more RWHP can one expect just by swapping the stage 2.5 5.3 to these

That would probably depend on what cam you had to begin with. So basically what would the difference be between these two heads (5.3's and the 215's) with something like a 224r?
