I've got a set of 186 castings that have brand new stainless 2.02/1.60 valves, brand new bronze guides also, these are fresh out of the machine shop.I have the receipts to prove the work.these heads are setup for up to 600" lift cams,and are FULLY ported(not a hack job either very clean) Ive just decided to go to roller cam so I will be buying aftermarket heads.Located in Dickson Tn. (615)428-3489 I will try to get pics tomorrow
