GM Double-Hump Heads $700
Sold as a pair.
These are double-hump heads that came off of a Chevy small block 400 engine. The engine was put into an IMCA Modified, raced once, and then put into an IMCA Stock Car for 25 nights. They should be able to be used for a street rod engine.
Numbers on heads are: 3890462 H106
They were cut out for big valve springs (stock diameter springs). It had 2.02 intake valves and 1.6 exhaust. Ports were massaged, and the valves, springs, retainers were all new when assembled.
There are no mounting holes for alternators or power steering pumps.
I am not the original owner of these heads, but I obtained my information from him.
