X Head Assembly & Installation - Comments Requested

For intake I am using Fel-Pro 1213. Fel-Pro 1213 Intake Manifold Gasket Set https://www.amazon.com/dp/B000CNNHQ4/ref=cm_sw_r_cp_api_ylu2ybEEJW6YW

Is there something better?

I don't mind getting new bolts. Can I use grade 8 for a place lice fastenal?

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.
