i'm getting ready to go the all motor route on my truck this summer and i am very interested in getting some new cylinder heads. i was gonna go all out and i was looking at the patriot stage III heads. what kind of gains should i expect from these and is there a better option? for example, milled 243's or P&P and milled stockers.

 

243s milled just got mine

 

i talked to a local guy here with a machine shop specializing in cylinder heads.

he claims my stock heads with a 5 angle valve job, port/polishing and a small mill/shave......about a 25-30 rwhp gain. i have ridden in cars with engine combos he has put out , and he knows his ****!

as far as 243's or patriots, i am almost sure they outflow/outperform stock heads, but i wont know until i try them!

 

i went from 12.49@almost 105mph to 12.20@ a little over 110mph. get patriot to weld and recut the heads to stock size chambers or smaller to bump the compression

 

one time i took a big dump and lost three pounds.

 

I'm still having a hard time believing that if you're using the stock truck intake that you will benefit that greatly from heads that outflow what the intake is capable of.

 

Stage 1 weight reduction?

 

What vehicle is it going on? What engine? What are the specs on the patriot stage III?

 

the stage III's are made for a 4.000 or bigger bore, so unless your building a stroker, look into the stage 2's

 

With my 6.0L when I changed to the Patriot heads with the truck intake I picked up a .10 at the track. When I went to the LS6 intake I picked up .20 additional at the track.
