Just make sure the 2 year warranty does not have any disclaimers for a 'self install'. Not familiar with the components mentioned, perhaps more knowledgeable member can provide advice. I would not want to go beyond building up from a long block unless I had a knowledgeable mechanic who I could rely on.
They won't do the install there so hopefully it's a half decent warranty. I will be sure to read all the fine print. Guy I'm putting it with is not a toyota guy in particular but he is a certified honda master tech and used to build late model racecars so I think we should be alright.
If not there is a good shop in town quoting me $1k labor to swap the engines.
