Any of you guys interested in doing a Ported Heads GP for you truck guys? We can get completely ported heads going on exchange for you 5.3l/4.8l guys & even the 6.0l guys

IM me for pricing

 

PM sent!!

 

im curious lol... cant afford, but something to think about

 

What are the gains?

 

are we talking just porting or full valve job with porting?

 

How about some specs and info?

 

the info i got was just for porting.. no valve job

 

will you take an iron 6.0 head in exchange ???

 

Sorry I'm slow getting back to you guys! We can do either just cnc or cnc & valve job Here's some pics & specs from the 1.5 & 2.5 heads


I promised everyone I would post additional pics & specs for both the PRC Stage 1.5 & 2.5 cylinder heads.

First The Chambers:
62cc Chambers CNC'd to 3.900" Bore

Valve Options:
2.02" or 2.04" Intake Valves
1.575 Manley Exhaust Valves (2.5 heads) or 1.55" Truck Exhaust Valves For (1.5 Heads)

This Pic Gives You A Look At Both The 1.5 & 2.5 Chambers With Valves:


Intake Port:
Runner Size 218cc


Exhaust Port:
Runner Size 80cc

or

(Platinum Spring Shown Here-->


We basically went in with the new retainer & gave us a little more pressure so guys can run bigger camshafts, more boost, or more aggressive lobes without risking valve float.

The castings are brand new GM heads that we receive fully assembled & tear down for cnc porting
