A little update. Tim has my heads almost ready to ship. Not able to download and send flow sheet, but they flow 442@.700 and 471@.850. Its looking like the cam will be just under .750 lift, maybe .725 after lash. Used Manley Nextec springs set up at 1.950. Looks like should be 225# on seat and .610@.730 lift. Once i get them, i can cc chambers and send that info off to Best Machine and get the pistons ordered.
