I have one more set of #186 fuelly heads . They are low mile heads untouched 194/150 with the front bolt holes . I bought the 4 bolt 350 block from a Corvette guy for $50 bucks . I asked him what happen to the heads . He said there in the corner of the garage . I said COOL $50 bucks more I had them . I Like fuelly heads for a under 400 HP SB Build . But I do not want to spend tons of cash building them . Last set I did I used Screw in studs that did not need the bosses cut down . And a mild pocket porting with new S/S 194in/150ex valves with a set of Z-28/LT1 springs . They were good to go went on a 355 with the XE268H Cam right around 375 HP . This is what the screw in studs look like . COOL
