I guess we should ask what kinda buget you on ???? Its pretty darn hard to beat having your own "seasoned" cylinders bored to 95in, Use some flat top SE pistons. When assembling the engine check the deck ht at TDC. I run my pistons .000-.005 out of the hole you need to check the quish clearence, you need about .035 when said n done. Send stock heads to be worked on. Run37 cams or woods tw7-h cams. do this and if you have the rest of the tune up you'll get the numbers your looking without breaking the bank.

 

Another vote for GMR Performance. I am more than happy with the way my Power Pack 2 build came out that I purchased from Steve @ GMR. It revs fast, and pulls very hard. Yet, it rides tame when you want to.
