Valve sizes in aftermarket heads
Hey guys, I will be getting aftermarket heads in the future, and I'm looking at either Patriot Performance, or Fox Lake Power Products. All I could find on their sites is the flow rates in CFM with no listing of valve size. IfI purchase aftermarket heads I would at least like to have2.02 int. and 1.60 ex. valve sizes. Does anyone know what size valves these companies use or know where I could find the info? Also, can we even fit 2.02, 1.60 in our little 2v heads? FYI my car is a '00 GT w/exhaust and a procharger. Thanks in advance.

Oh, ok thats cool I guess. What brand did you go with or did you just have your original heads done? I'm hoping to get around high 400's to low 500's at the wheels eventually, do you think w/my P1SC and lets saylike Patriot Performance heads Stage II could be feasable?

Livernois & Steen are worth checking into as well as the fox lake.

Thanks guys, I'm getting some much needed info. I definately plan on forging the bottom end as well as getting either the P-51 intake, or the new Logan motorsports design. Dang, so many mods, so little money[>:]
