Sold in mini-sets here. http://www.oreillyauto.com/site/c/search.oap?keyword=gasket&year=1966&make=GMC&model=Suburban&vi=1493101

If 305 is similar then http://www.oreillyauto.com/site/c/detail/FEL0/FS7961SB1/02287.oap?ck=Search_02287_1491808_-1&pt=02287&ppt=C0026
Bores are different but maybe other gaskets will work? I'm not sure. Others will know. The first link seems to cover a lot of gaskets. Some of the parts below indicate applicable to 305 and 351, so seems like some internal bearings and such are the same. Same crank? I don't know.

Above Part Numbers must be confirmed, just my shot at it. Not sure what bearings you wanted. Please always be specific in your questions. :signthankspin:
As you see ,the secret with someehat hard to find parts, is to get a good part number and google all the sources that still have the parts in stock. ALSO, Jolly has part numbers on the Legacy page...NICE!

Commentary/opinion: Be aware that many V6 parts are hard to find and getting harder. Rebuilding these motors can be challenging. BE SURE you locate all the parts you may need before teardown. Then buy what you need. Locate means actually talking or emailing a real person who eyeballs the part. It is getting that critical I believe. Always keep your eyes open for a cheap good running donor motor near you if you plan on keeping the V6. Beside the cool factor, rarity factor, awesome to look at factor...THE MAIN attraction for these motors is the longevity. Very well engineered to last. So don't rebuild just for fun. If it ain't smokin or knockin, don't fix it. Pop the expansion plugs, flush and replug, rebuild carb, give it a "tune up", replace necessary external bolt-on parts, do a compression test, put in a new oil pump.
Accentuate the operative, but don't mess with Mr. In-between.
Other side effects may cause nausea, loss of fluid, wheezing, lack of power, backfire and premature...... never mind.
