Thanks, Pat.

I hadn't thought of a rev-kit - that's a very interesting idea. But, I looked up the Isky site and they don't seem to list one for a BBC. Comp Cams do, but say it's only for solid rollers... It is possible to use a rev kit with hydraulic rollers, is it? Wouldn't they tend to collapse the lifters?
Can you steer me in the direction of an actual part # from any of the manufacturers??
