need info on my dove c heads ...want to use solid roller cam

what am i gonna need to do to be able to use a .640 - .700 lift cam

ive got the lifters

i know i need the heavier springs , but my valves do they need to be longer and as the guides go ??

I am running dove-c heads with a .649 in .642 ex solid flat tappet not the roller but I had to cut the valve guides for the higher lift I cut them to accept a .675 lift.Plus had to cut the spring pocket to accept the heavier and larger springs.Hope this helps I bought the cutters and did all my own head work cheaper than I could get it done around here.

any idea what any machine shops charge for this idea

All charge differently,you will just have to make some calls.

X2 and don't forget to get New SS Valves, Stock stuff will not live at the higher spring pressures.
