Im stuck between TSP/PRC heads, Patriot performance heads, or Dart heads.
I have a C5 with long tubes, (no cats), Corsa Indy exhaust, Intake, and will have F13 cam on a 112 lsa installed with a yank ss3600 stall. which heads out of the three have had best performance/dyno #s etc. any help is appreciated. thanks

 

Well those heads are like comparing apples to grapes to oranges.
Your best bet will be to search each one individually and then compare your findings. I know that there is a lot of information about all 3 on this site all over the place.

 

I'd go with the Dart 205s. You can get a 62cc chamber which I've been told will get the compression close to 11:1. They aren't a whole lot more money than the LS6 heads. If you wait a bit, Patriot will be coming out with their own seperate cast heads. Here is a link https://ls1tech.com/forums/generation-iii-internal-engine/466212-patriot-predator-heads.html

If you want best bang for the buck, the PRC CNC LS6 heads from TSP have shown good numbers. But, I'd spend the extra money and go with the Darts

 

That about sums it up, if you want to go for the cheapest(in price) go with the TSP LS6, but for a little bit more you can step it up to the darts, even though they are pretty close, the dart is a completly new casting and is bare.

This will give you a lot more options in the end. The new patriot heads look interesting.

 

If you are leaning towards a budget head, our CNC ported 243 castings are a great option. These heads flow very well and have a smaller runner volume than other ported 243 castings on the market. We can do a set assembled with 2.00"/1.55" oem valves and our Patriot Gold springs for only $1125.00 shipped to you anywhere in the US. This price does include a free set of OEM head bolts. These will work well with your set up.
