Go on WWW.northwestvintagespeedsters.com
There's a lot of flatheads & overhead conversions that I've never heard of! Bill W's Ghost

Thanks Ghost,
I lost track of that site and and got a "Could not find" message with the link you gave. It was close enough though and I found it under www.nwvs.org. |

Rallum was made by the Reus Bros out of Baltimore. I had a Reus head but sold it to the Smith Musuem. Got $700 for it. Made in the 30's. Ken

This a very late response to my own thread, I did buy the Rallum head and it has been sitting in my garage since I first posted. I shot a few pictures of it to place it up for sale but though I would post here first. tim

Screw in a spark plug, buy a CC tube, fill it with sugar, then pour it into the combustion chamber to see how many CC's it takes to make it level. Compare that to an original head.
