Glad you found something workable. I had a feeling Cat would be a PITA, especially for anything out of their ordinary. The machinist who rebuilt my heads ordered me a set from McMaster-Carr. The long bolts are a 1/16" short at 4" even but since he took 0.007" off the heads to make 'em flat the 4" bolts will be OK.

I used a stud set for Mopar, small block, to get the stand off studs for a windage tray.  They are a little longer than the main studs I got from Mummert a long time ago.  Mopar main bolts might work but because of that extra length, you do want to check to ensure that the bolt doesn't bottom out or block off oil passages before proper torque can be applied.

Well I will have plenty of washers. I didn’t know ARP included the washers with the bolt packages. You don’t need to buy the washer packs I listed before

While Paul contacted me directly regarding what the ‘FT’ designation means in relation to the grade value, I was not able to help.  While the grade five and grade six bolts do have slightly smaller shanks than the grade eight bolts, the ‘FT’ bolts do have the same shank size as the grade eight bolts.  Based on that alone, it’s easy to surmise that the ‘FT’ bolts are grade eight without any additional information or testing to point elsewhere.  Nowhere in my literature is there any reference to what the ‘FT’ bolts are in regards to their grade values.  Any additional information regarding this is welcome.
 
What is interesting is the recommended torque values for the various grades of bolts.  The 716" grade five and grade six bolts are being pushed well beyond the factory head bolt torque spec recommendations based on the following chart.
