If you are doing a complete re-build then you will be installing a new cam and lifters correct ? Is this just a basic re-build or are you planning on added HP ?
What parts do you have or are planning on getting for the build ?
Really need more info on the use of the engine. IMHO

You fail to mention which heads you have. No really relevant, but "nice to know". If all the parts are "original", I would certainly replace the valves, springs and locks. The retainers are pretty tough. Not expensive, though.

That era of small block is known for guide wear. Be sure a competent machine shop inspects the heads thoroughly. A "valve job" IS called for.

If these are 1968 heads. As mentioned, You will have to check the guides and if this is to be a "working" driver engine. Hard exhaust seats will have to be installed. Rotators installed, with springs to compliment the rotators. Probably cheaper to get some late seventies early eighties heads.
