Well I got a good deal on it I thought $125 bucks. To be honest I didnt think it was that big of a difference .. me being a rookie and all.....But I guess if It doesnt work Ill repost it on ebay for sale. But my block hasnt been decked (or at least thats what i was told) and the heads havent been shaved either. They are new, but how would a guy like me figure this out???
