Take your camshaft and send it to delta camshaft in Tacoma Wa for a regrind. Also if you have solid lifters,send them too, so they can machine the bottoms for the regrind, run you only about $150. They will also sell you a quality timing gear setup too. I have been using them for 40 years. Cam cores are getting scarce so they might not have an exchange necessitating you sending yours in.
