I have been trying to send this for awhile, maybe it will work this time.
I'm making chips doing a billet aluminum head for my 32 Plymouth. Converting
back to "L" head. I plan no water jacket mostly because its easier that way.
My thought is there is no exhaust passage in the head and it will have 16
fins 1/8 thick by 3/4 tall with 3/8 gaps between them. Any input on this
plan, informed or otherwise, is encouraged. Also I will be using two 10 mm
sparkplugs one in the normal place next to the exhaust valve and one over
the bore. Thought it would be interesting to vary the timing between them to
see what happens. I am sure all of this was done 50 years ago but it keeps
me busy. Rich Fox
