Mystery cylinder head - Henry Harris - 24-03-2021

I've had these un-machined cylinder head castings for more than 20 years and can't remember where they came from.

The possible suppliers were Barrie Argent, Alan Raeburn, Paul Bonewell or ????

I dont know what they looked like but Lester Reader, long time owner of the Rubber Duck car in NZ, made a batch of two piece heads probably late 1950s. One of his special builder mates was a pattern maker. All had a workshop a few doors from me when i was running my RP as a teengaer early 1960s. They had outgrown Seven specials by then. Lester died about 10 years ago.
(I presume his exploits found their way into the UK magazine)

The only question I have is where do the spark plugs go without intruding into the water jacket?

aaargh! TWO head gaskets?

Umpteen years ago Alec King, longtime 750 member and trials exponent showed me a casting pattern and coreboxes he had made that would have resulted in that style of head. I remember being particularly impressed with the "loose piece" which allowed the plug recesses to be cast in to a shape which otherwise wouldn't have drawn from the mould.

It's a diesel conversion Bruce...

Touché !

RE: Mystery cylinder head - flywheel1935 - 24-03-2021

looking at the inside of the casting webs my £5 is plugs in the side at about 45 degrees ???
seen something similar a few years ago, but now days I guess a CNC billet would look good too. (or 3D printing)

I think Tony Betts sold a two piece head similar to this a little while ago
