Hello fellow MG enthusiast. It has come to my attention, that there was one year only, where MGB used a larger valve head on the 1972 MGB rd/gt. If there's any MG buff's in the know, about said type heads, I would very much appreciate, any and all information concerning these cylinder heads. Why they was produced, and reason for there introduction in the MGB, The size of valves on this particular cylinder head, etc, etc. I'm hoping someone might shed some light on this for me. Happy motoring, and Safety/Fast. Looking forward in hearing from you. Best regards, Ken

Haven't heard about a single year cylinder head, but it sounds like a 2923, which was used 72-74.5

I don't know. It's always smoked like that/made that sound/done that.

The 2923 is the best stock factory head made as for flow, but it also one of the prone to crack. The 2923 had the largest valves of all the B series heads at 1.625" vs 1.56". However if you port ehad, you can make it whatever your need to be,and even go up to 1.7" intake valves.

There are few heads to add to the bunch that were only Euro market only heads, I talked to Peter Burgess about this one time.
