On a na 5.3, would the hp/tq differences be negligible? Trying to decide between the 2. 600$ more for the trickflows isnt a big deal, but if its a 5hp difference ill put the 600$ towards a lsxrt. Thanks!

 

Believe it or not, I am running PRC heads, but given the opportunity to purchase again I would never get PRCs. I would get the Trickflows in a heartbeat.

 

I run PRC aswell and they have worked well for the price, but if I could also do it again I would have went TFS

 

Cool. On fords ive always ran tfs heads whether dragracing mustangs or a 521 a460 mud bogger and ive had good experiences! Whose springs do they run?

 

TFS for the win

 

I have the prc heads and i love them. If you decide to go with the TF 205 heads when i was looking Liverois Motorsports had the best price for them.

i noticed a big difference up top with the PRC heads

 

the 205 head will give you a ton more power down low and through the mid range than any ported factory casting. They flow as much air as the CNC factory casting, but do it with an intake runner that is smaller than stock. Impressive.

 

whys that if I may ask?

 

I have just seen a lot of vehicles that run real strong with TFS heads, track and dyno.
I am saving my pennies for a set of 245s
