Now that I know Pro comp heads are junk has anyone used Patriot heads? They are made in USA and fairly reasonable about $1400 assembled a pair on Summit.

I used a set 2 years ago on a 540. They were the "freedom series"? I had them lightly ported and intake matched. The motor made over 680 HP. They been on ther same engine and running great for 2 seasons now. I would recommend them.

I have owned both. I am no expert but this is what I observed
1. Patriots casting is much thicker and total weight is 5-6 l s heavier per head
2. All the valves line up perfectly with the pushrods/guideplates on the patriots. Not so on pro junks
3. Patriot has a plant that you can call for tech help that is very good (ask for Stephen)
4. QuAlity is much better (my opinion) on the patriots
5. Make sure you change out the exh valves to inconel
6. Performance is super on both
