Although that link didn't work.. I do like the Felpro print-a-seal gaskets. I add RTV in some places like at the 4 corner water ports. I couldn't buy gaskets through Amazon, ebay or any mail order. Who knows what quality I might receive. If I buy from a local part store I at least know they were properly stored and handled. Some online sellers may have ancient stock stored in mini warehouses, poorly stacked, walked on, who knows?
As for head bolts... I buy a set of head bolts, Summit, Jegs, RockAuto, wherever is the best price. I don't expect hard parts like bolts to arrive damaged.
