Chi thanks alot for all the info and getting back, it's def appreciated. That's what I have heard so far to be the more common method, of breaking it in while staying out of vtec. Hoping to get my motor out the machine shop soon.. been there a few months.. bottom end balancing and block assembly is all that is still missing!!!... then I can get this to my builder and start the swap!.. I am planning on getting my ECU calibrated and adjusted for the rc370cc injectors before firing the motor up as well..I'll update it again once I break it in see how it goes..
