Paragon sells both the "FP" and the "A" intake bolts - use whatever the Judging Guide calls for.
Several different recessed-head flanged bolts/headmarks were used for the bellhousing-to-block attachment, and "FP" was a typical headmark. Same story for the plain hex-head zinc-plated trans-to-bellhousing bolts, where "TR" was a typical headmark.
As there were sometimes differences year-to-year for the same attachment hardware (which Paragon points out), you need to do your own independent research - they don't have all the Judging Guides.
