Going to take my pistons to machine shop to have them fly cut for a larger cam. When the block was being cut for fire rings they decked it and eneded up taking .008 off the surface. Should i be concerned about piston protrusion or is that enough to even make a difference. Block has never been machined before, going to use the original pistons, fire ring gasket came from haisley.
