340292 was available from GM "over the counter". This version had angle plug configuration, 2.02/1.60" valves, 64CC combustion chambers. These were known as the "Turbo" heads. I have one of these. They are very rare. Date G 5 $400

"492" – 3991492. Another good performance head. They were found on 1970 LT-1 engines. They had 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 62CC's. These heads have double hump casting marks. This particular casting head was also available as an "over the counter" head from GM in straight or angle plug configurations.

Default 461 heads

Sent (or thought I sent) a PM yesterday. Very interested in 461 heads and would like a bit more info. Thanks!

Oops, narrow focus on my part- the early '62 casting date 461's

Are you sure the 492's have 2.02 valves. I thought they were 1.94's. Can you measure them so I know for sure? If they are 1.94 I'll most likely take both pairs.

One set of 1.94 straight plugs, 1 set of 2.02 angle plugs.
