These Heads are used on our LS7 Engines. Both are used in Latemodel and NE MOD Type Racing. We noticed a couple things early on working with the LS Platform on circle track engines. All the available heads were to big runner wise. They were all made for drag racing or any other form of racing. The 2nd thing was the water was not correct which would cause overheating. Once we figured this out, then we knew we had to design our own head. This head turned out great, Makes awesome power, & drives good. We also got the engines running cooler. If you are building an LS Platform Oval Track Engine, I highly recommend these. It will save you a bunch of headaches.
