These are a pair original GM

1970-74 SBC Double Hump Angle Plug Heads

They are in good condition, would freshen them up before use. These came off
of a good running 1970 LT1 motor. They have the 2.05 intake and 1.06 
exhaust stainless valves in them. A lot of professional port work was also done.
On one of the heads it had a burnt spot between two chambers which was
professionally repaired. The other head had epoxy installed in one valve spring
pocket on the inner edge. These repairs have not affected the performance
of the heads since they were used a long time after the repairs were done. 

GM #3991492
Both Dated F 12 4   


**Will be listing a set of polished aluminum Brownfield heads soon**
