TEA Trick Flow heads initial impression

I think when you look at the quality, flow, power and bolt on ability it's a hands down winner among the currently available aftermarket heads on a 5.7 engine. This head actually has BETTER geometry and better piston to valve clearance then a stock head as well. There will be a LS2 version available soon as well as a 402-408 version, the latter version will probably have a +.400" raised valve cover rail as well. The best part is there will be practically no wait time on these as well.
