Their just back from the machine shop. I had these checked for my own piece of mind. Ported by Muscle Motors, flow 320ish and 250ish. These have roller cam springs that were checked and are within spec. Comp 943 springs. They were milled some. 73.6 cc. Valve job done. Guides were good. New seals retainers and locks. Ready to bolt on and go. $2000.00 usd shipped and insured in Canada or the lower 48. U pay the pay pal fee or send me a moneygram. Thanks. Kim
