I received my Patriot Performance Stage II 5.3 Heads last night. They are awesome! The difference is amazing. Thanks Gunnar! Patriot Performance has awesome customer service and great products. I'd recommend them to anybody who is looking for quality heads at a great price.

I will post some pics of them later today when I get off work. Until then, here is the flow numbers.

Lift-- .100 .200 .300 .400 .500 .550 .600

Int. 73.8 -- 142.7 -- 200.7 -- 242.4 -- 279.0 -- 289.1 -- 296.2

Ext. 61.5 -- 108.8 -- 148.1 -- 185.1 -- 209.5 -- 216.5 -- 223.1


These are with 2.02/1.57 Manley valves. How do they look?

Oh yeah, these are going on the 382 LS1 I'm building up.
