I have a WF engine with an ANMod01 cam with 1.3 rockers, shaved head, oversized valves with green stripe springs. I believe that the valves are floating at around 7k because it starts blowing fire out of the exhaust and spitting out of the carb. The lash is not too tight. What springs should I use for this? Or what changes should I make if that is what is needed? Timing is 34 deg on alky. Carb is tm24 mikuni. All help will be appreciated. Also, if anyone has a similar setup what jetting are you using?
