How did your custom cam modeler do the job without knowing for sure what the compression ratio was?
The stock pistons in the 93 are hypereutectic -- they don't like the combination of boost and detonation; so keep your tune conservative (rich) so detonation doesn't occur. Rods are plenty strong. The weak links for you are pistons, and the stock block.
Grn92LX said:Its the tfs valve springs they don't recommend going over .540 lift. You'll be swapping them out for real springs regardless. Now, those pistons I dont know much about. Do they have deeper reliefs for large cames and valves? I would swap those pistons out for something that you know will work and fit those heads and a larger cam. I like probe pistons because their cheap and have deep reliefs for TW and inline valves.
I'd upgrade to arp rod bolts along with whatever necessary work to make the arp bolts work.

And just incase you don't know, Speed Pro makes both hyper pistons and forged, you didn't say which you were getting.
