Default Precision Race Components CNC Machine At Work!!

Here's a few quick pics of the Precision Race Components Haas 5 Axis CNC machine porting away on some 5.3l castings




Each set of heads are completely cnc ported on PRC's Haas HS1 5 axis CNC machine & then assembled with great attention to detail! When comparing cylinder heads take a look at the features & components that go into each brands cylinder heads! PRC uses BRAND NEW GM Cores, name brand Manley Valves, PRC's Gold OR New Platinum Series Race Springs all for a awesome price of $1529 for 2.5s or 1429 for 1.5s! Here's The Specs On The Heads:

    Jason, these heads have shown a 50rwhp improvement over stock 251 casting (01+) LS1 heads, correct? So we're looking at maybe 38-40rwhp over LS6 heads I presume?

    Hit us with some numbers. Thanks.

    Jake I would say you will typically see about 40rwhp from a good cylinder head.

    Nice price! Do you have any flow #’s?

    Who designed the ports, and what are the volumes?
