Yea, sorry, brainfart on my part! Rich has offered nothing but solid advice from the get-go.
Rich had told me , probably a year ago now, that the engine would be XXO. However, being the brainiac I am, I overthought it. When I read it, I thought it meant I HAD to have an overhead valve( speciality), modified engine to qualify.
Then, being even smarter than before, I thought it contradicted itself by saying NO speciality head.
