Lower Intake Manifold Bolt Kits?

I'm getting around to fitting my 5.0's lower intake manifold back on my truck. Given the poor condition of the bolts I took out, I thought I'd replace them all while I was at it. Initially, I thought I'd use a standard Mustang-intended kit, but I thought I would check and see if there's any better truck-specific kits or sources for all the bolts and perhaps the four studs. Any recommendations?

the lower bolts would be all the same pretty much with the exeption of acouple being studs. i used a stud kit on mine so i dont have to worry about breaking the bolts off in the future

When I did the exhaust on my 4.9L, I picked up new studs at NAPA. They were hanging on the card display with all the other fasteners. For, essentially a 1 time buy, they were not expensive.

I used studs, washers and nuts I ordered from the local fastener store (Tacoma screw). I like using studs for the lower because it greatly helps keeping the intake gaskets in place when putting the intake on.

Is there a cheat sheet on what all I'd need to locate?

I didn't take any notes and I did it years ago, but I am pretty sure this is what I did:
1) measure the threads, diameter, and hole depth head side.
2) placing the intake on measuring how long the studs need to be including double thickness hardened washers and ensuring there are at least 2 exposed threads left after the nut is cinched down.
3) went down to the store and bought them.

Keep in mind the threaded length of both ends of the stud as well as the non threaded section when measuring the length needed. Short head side threaded length can lead to the stud being a little prouder of the manifold than expected.

Also I prefer finer threads on the manifold side of the stud.

Looks like ARP make a kit too:

ya ARP sells a stud kit but its like 60$ ARP 354-2103. theres some cheaper sets on ebay also such as these
PC Ford SB 289 302 351 Windsor 12 Point Black Oxide Intake Manifold Stud Kit | eBay

otherwise take a bolt to fastener store or maybe even an ACE Hardware and get some small sections of all-thread with the correct thread and get some nuts. my ACE has small allthread sections around 3" long sections which may be long enough
