[Fot] 1500 Spitfire Head Thickness?

[Barr, Scott]

I've seen a couple of lists of cylinder head thicknesses, compression
ratios, etc. floating around for the 6-cylinder cars and (I think) the
TR3/4 motors.  Any chance there's something similar out there for the
Spitfires?



I've got a later Spitfire head (god knows what year, but it's got the
air injection ports) and I'm trying to figure out its original thickness
compared to the present 2.906" thickness, so I can determine what length
pushrods to order as a starting point.
