Be very careful on the spark plugs. I forget exactly what it was but there were 2 sets of plugs for that head and one had a longer set of threads and one had a shorter.
I found this out the hardway when I blew a plug right out of the head! The local svt dealer will know what i'm talking about. They didn't even question me about it and just put a new head on the L. Gotta love the warrenty.
