Cast iron guides are cheaper to manufacture. Bronze guides are more costly. Is there an advantage to bronze? Probably longer wearing, but I would be happy with cast iron. Zillions of Chevy motors were produced with cast iron guides.

cool rockin daddy "You need to take a look at the GMPP Bowtie vortec heads.

Big 225CC port and small 185cc port. Ready to rock or bare.

This is the best true Vortec head on the market.
They are way ahead of the stock 062-906 truck heads and all aftermarket cast vortecs.

You and I own this company (thru your and my government)
You might as well buy their (your) products.

The price is right. North American cutting edge designed and made."

Right on! I have been touting these heads since they came out. Am saving up for a pair of them now.

86GMCK1500 alright thanks for the feedback guys, I'm wondering what am I gonna get in differences between the different intake ports for instance 185cc to 225cc and the different combustion chamber sizes

04SilveradoMykk I use Patriot 'Vortec' heads on my engine. I've been happy with them. They've been reliable and are nice step above stock. I don't believe they're advertised flow numbers on the website.

I've found the patriot vortecs need a couple more degrees of timing compared to GM vortecs to really shine. The intake valve is so big that it goes beyond the combustion chambers. And even hangs down a couple thousandths lower than the head surface. I get the impression these heads are released to the public with the intention of spending some time under a grinder/bit to really clean them up. I also needed to mill .008" off each head to remove the extremely rough cut milling job they were shipped with.

These pics are of the heads as they arrived to me, one pic is post clean up mill. No port, bowl or chamber work has been done.











The heads I received are made by patriot but sold by an online retailer under their name. I am unsure if they got shipped to me by patriots specs or with the third parties valves, springs..etc.

The springs that came with these heads were meant for a flat tappet cam, I used Comp 26918 beehive springs for the correct spring pressures for my Comp roller cam.



I've also discovered that these heads with a XR276HR10 camshaft work much better with a RPM dual plane intake instead of a big single plane.

techinspector1 Racing Head Service cast iron guides #12407-01 or premium guides #12410-01 instead of L31's. Thick wall casting, set up ready to bolt on out of the box. No jacking around or machine work like you have to do with L31's.

Some fellows say that the casting is generally OK on the Patriots, but the components used to assemble are not the best. Buy the bare heads and assemble them with good parts.

patriot heads?

So far I been researching what kind of heads I want for my sbc 350 and Im looking for 062 Vortecs with a 64cc combustion chamber. Anyways I was looking at patriot heads...http://www.jegs.com/i/Patriot+Perfo...3/2151/10002/-1 but after reaearching they seem to get a bad rep..what do you guys think? What about RHS heads and of coarse I know you get what you pay for but I will be using it as a daily driver not something only for the strip..
