| Thanks for the input ... A built motor would be nice, but I think I might have to wait a little while longer for that. As aliaZ said, I live in Canada and paying shipping and brokerage fees everytime I purchase an item gets expensive. Should I win the lotto I will be sure to purchase items from ALL Z Vendors! For now I must be practical. Is it worth the time to pull the heads to replace the head gaskets. Doing this would go beyond my limited auto-repair ability and would cost significantly more in labour fees should I pay someone to do it. I hope this set-up will last for 2 or 3 seasons @ approx. 5-7 thousand miles per year. Boost will likely be limited by the 555's. A fully Built Motor will follow. A few seasons on the 675's will give me a good idea if I'll be happy with that HP range. If not bigger turbos can be bolted on to a built motor when the time comes.
