Thats what I'm talking about!
I don't think I've seen an LSX build on this forum since I've joined it. A lot of people go with the L92 cylinder heads on LQ9 builds. You should definitely see some good gains with the mods that you've already listed. I read that the pushrods in the L92 are weak though. Pay a visit to LS1Tech.com to see some LQ9 builds. Is this a stroker motor? BTW welcome to the forum and I would love to see some photos of your car and of the engine that you're building.
