Tools used for porting this cylinder head

Do those flex-shaft die grinders have enough power for cast iron work? won't they stall?

Beyond the shadow of a doubt these are used in all sorts of hardened metals. Flex shaft tools will have more torque and power than anything else you're trying to look at in the lower RPM Rangers

It's a plan man. Just let me know over on 2 Stroke Central and I will hook you up.
