You're feedback's been very helpful, and raised some new questions. On this 1980,30+ there are wire halyards. Does that mean they'd need to be replaced before I can run lines aft? If so, would that involve changing the size of the pulley at the masthead? On a modification like this, could you relocate the winch on the mast to be used on the cabin top ? I'd also really like to add a spinnaker halyard,but there's no masthead block for that. Anybody know what type of set up I'd need for that? The potential of this boat seems to be calling to me!
Thanks again.

Your boat sounds like it was originally sold pretty much 'box stock'. After all these decades that's a good thing, as you'd otherwise be considering replacing out-of-date gear in any case...
Our '88 has the standard-Ericson-Kenyon spar, through stepped. Perhaps yours is similar.
There might be as ss plate around the cabin top mast opening to which you would shackle turning blocks. Then those lead the lines outward to some sheaves in a flat configuration and then aft through clutch stoppers to a housetop winch. Does your boat have any winches mounted on the mast now?
I will try to get some photos of our boat to post for comparison.
Our boat had old wire-to-rope halyards as well. We found some meathooks in them and replaced them with all-rope lines about a decade ago or more. There are some good threads here on how to accomplish this.
I would bet that your masthead has provision for a spinn. halyard block or even it might have slots and sheaves for port and starboard "wing halyards" like our spar.
Do you have some exits above the gooseneck area on the spar that are now unused?
Maybe best for you to attach some digital photos of your present cabin top, mast base, and the side of that spar. Use you telephoto feature and some enlarging/cropping to try and show the mast head.
Much of the house top work just calls for planning and thinking through the details well, and I believe that any patient amateur can do an excellent job. (The pro's can do the work in less time, but for $75 to $100/hour... Yikes.
And sometimes the "pro" you hire is only slightly better at it than the owner! And once in a while, is not as good.

Don't know about moving the halyard winches...If your halyards are original the rope part is probably twice its original size from years of accumulated salt, dirt and wear, as mine are. If you lead them aft you will probably want to add rope clutches. Rather than buy the larger size clutches I would replace the halyards with all-rope. You may be able to use the existing halyard sheaves if they are in good condition and can handle 3/8" line; if you want larger sheets you may need new sheaves. My rigger looked at mine and judged them good to take 3/8" lines. Also, if you lead the halyards aft you may find them a little short in the cockpit since they were sized to be on the mast.Since the 30+ is a fractional rig, there is a sheave box on the front of the mast where the forestay attaches. There are several sheaves in that box that can be used for other things like a spinnaker halyard.
I would go with very low stretch 5/16 line for a boat of that size. Probably better fit the original sheaves, too.
There might be a sheave box where the forestay attaches as Mark noted. Port and Starboard "wing halyard" arrangement for flying sails like spinnakers. Might be an extra exit plate on each side of the mast lower down, too.

It's all coming clear(er)! You guys are great. Loren ,thanks for the pictures. I was picturing a mast head spinnaker. Am I correct that with the fractional rig you don't do that? So, the spinnaker halyard exits either spot beside the forestay? So, on one tack it will be laying over the forestay? Maybe no issue if it's eased a bit?
This is ALMOST as much fun as sailing!
Thanks again,
