198 Rods + 2.2L Pistons - advice needed

There's a lot written about using 2.2L pistons and longer 198 rods in the 225 - has anyone documented the process beginning-to-end? I read Dutra's stroke article which is great, but I'm wondering if any improvements or part options occurred since that was written. Or lessons learned.

Looking for deep advice - especially on part selection. Rebuilding an NA '68 225 for 230+ HP - street use only - not a redlight racer.

Parts planed so far: OCG #346, 1.7 & 1.4 valves, 300# springs (says OCG), about a 3.5" bore, 10:1 compression, Edelbrock 500 AVS, 6:1 headers. Hoping to minimize milling by using this setup which will allow me to put more $$ into the head (port, bowl, chamber) to increase velocity and filling. Need to use pump gas (any grade but no additional additives like an octane boost) - fuel mileage not important.

Questions:

• Are some piston part-numbers/designs better than others for my purpose? I see some with a trough, some with 2 or 4 reliefs, flat-tops, recessed - any thoughts on which provides the best performance for my needs?
• Any special rod prep needed? Clegg and BP offer reconditioned rods, any preference in vendors work?
• Any special block/head prep (other than a light cut and runner/port blending)?
• Anything I didn't ask but should know?

Thanks as always!
