George,
Can you idle it down?
Glad to see it is running. Be careful wanting a bigger cam. It is also the head that is holding it back. Once you put a good flowing head on it, the response is about like putting a bigger cam in it.
Your lifters sound really loud. I always adjust with the engine NOT running. I have described it before in other posts.
Also 5w30 is too thin for your engine. It was never designed for that viscosity. I suggest 10w30 or 15w40 rotella.
