When I pull the heads off what modifications should I do to get the most out of my 1972 351 CJ heads?

I will definitely do screw in studs and guide plates for a .600 lift cam

What porting?

Gasket match both intake and exhaust?

Stainless one peice valves?? What brand?

Larger valves? What size?

Bee hive or cam matched springs?

Gasket match head gasket?

What else?

This is a primarily weekend cruiser 1972 Mach 1 4 speed. I am looking for the best modifications for the money. I will do all the head prep i.e. port, polish, gasket match myself. I don't mind the labor, it is relaxing.

Not being able to see your heads its hard to tell.. If they are like my heads where
it was only a little bit more money to get a set of aluminum heads (sometimes less)

Most will work as good up to way better...$$$$$

Check out the topic below this on the stock stroke Cleveland Brent built and that should give you some ideas
on how to prep your heads.
Also I would have him spec out a cam for you rather than you buy one off the shelf that might be less than ideal
for your combination.
Good luck

Thanks for joining the forum, good to have you.

The heads work great the way that they are and will support over 620 hp.

I would buy some nice 1-piece stainless valves like the Ferreas. The 2.190"/1.710" sizes work great. As you mention, you need to drill and tap for 7/16" rocker studs. If the guides don't need replaced, I would have them cut for a modern Viton valve seal.

Beehives work well, or a small OD dual spring. They need to be matched to the camshaft.
