thered have to come a time , when less f'ing around , to knock up a set of patterns , & core patterns , for a virgin to order cylinder head blank .
" If you could start with a 28mm port and create an "m" or eyebrow shape porting upward and wider (not removing material at the guide bore) similar to the harley port mold pics you would be 1/2 way there. Welding up the combustion chamber and adding a fin would allow you to relocate/re-angle guides, install big valves, bathtub chamber, and give you a raised floor to work with & re-radius. You would probably have to weld the sides of the head and re-route the oil return (external line) to get enough oval width. "
anyone there a retired patternmaker / carpenter ?
