From the valve stem guides? I know some makers use bronze. Maybe this is bronze and not brass or there are some makers who use brass and not bronze.
they are 1969 351w heads These heads have been ported, have screw in studs and guide plates,and crane roller rockers with posi-locks. The intake valves are 194s and the exhaust are 160s. Stainless exhaust valves and hard seats High performance triple valve springs. the heads where done by mondello's in ca i got them used
i think someone went all the way through when they were porting and brazed and smoothed it i got the heads in this shap off ebay what do you guys think the heads are worth with the roller rockers and every thing that i described?
