Guys
No cooling needed for methanol. I decided to keep as much standard as I could so cams, rocker covers, cam caps etc could all fit. Intake are 36mm exhaust 32mm - thats to get around 80% intake flow to exhaust - ideal for supercharged methanol. Its not all about flow - its about the gas path around the valve and getting good burn in the chamber. Exhaust is raised 15mm to give a better flow angle - and rectangle to suit the twin valves. Intake is a copy of the Hemi TFX type head - the more air in the better. I am going to try and modify the manifold I have, otherwise billet and billet rocker covers. 10mm spark plugs too that you can't see.
