is it worth the effort? (cam)

do try the cam advance and post your cranking compression
if you want to keep your rpm range consider a solid lifter cam
IMHO your regrind will make more HP and except at the very low end will have more torque
but I doubt that it is worth the $$$ for new lifters and pushrods
you could retard your current cam and find out how it would affect your low end and see if you like it
measure twice- cut once
cheers
If you do want to consider solid drop me a PM
