TSP / Patriot 5.3 Stage II Race-Series Heads (pics) Just got these bad boys in the other day. Hand finished, 2.055 intake and 1.60 exhaust valves, w/ Patriot dual springs. 
Should, hopefully, have the car up and running this week.

Brian glad you have your heads! They are actually Texas Speed Race heads, they are cnc ported by Patriot performance for us. They feature 2.055 intake valves, 1.60 exhaust valves & are the same heads that went 437rwhp with our new 225 cam

I too an interested in the flow #s on the Race Series 5.3s.
Do you have to flycut for the larger valves on say a G5X2 cam??
Will you get more for your buck going with the Race Ported 5.3s or the LS6 Style (59cc) Stage II heads without the port job?
