P4 and P5 Rovers also had straight six inlet over exhaust engines, as did the 6 cylinder Bentleys up to the 50s. It wasn't an unusual arrangement back then. Not sure why they didn't stick all the valves in the head though

So at different heights not like the A series in line inlet and exhaust in line?

As I understand it the exhaust valves were on top as they are for standard push rod engines like the a series and Ford Kent, but the inlet valves were underneath on the deck of the cylinder block opening upwards.

Nah, t'other way round, the inlet was in the head and the exhaust in the block. This allowed for bigger valves than either overhead valve or sidevalve engines.
Not only did Rolls Royce make a 4 cylinder version and the 6 cylinder used in the VDP 4litre but they also made an 8 cylinder and this will please @Drago that was used to power the stolley (stalwart)

They could use bigger valves if one was in the head and the other in the block.

Your quite right, somehow I mixed up the clue from the words when I wrote it down.

Apparently the other way up was also a thing,
