Just out of general curiosity and hypothetically speaking, im stoked to have my new heads finally sitting in my room. What do you guys think I can expect out of a power difference? I dont mean power overall exactly, but through the range as a whole.

They are TFS 215's opened up to 220's by TEA (I know, same company)
2.040 valves, flow chart says they went 325 at 600, my patriots only went 306

 

15hp maybe? Mid lift flow numbers is where the money is.

 

Whatever you gain I'm sure it will but a smile on your face.

 

Hey Detoxx, I meant to tell you something a while back...if you ever sell your Trans Am, don't plan on waking up the next day.

 

Lol I'll remember that if I ever bump my head and sell it

 

I removed l92 ported heads for out of the box trickflow. The l92 heads out flowed my trick according to numbers alot on the intake. I gained zero on the peak,stayed the same. But,i gained 20hp and 15tq under the curve. You will gain all over 15 to 20hp.
