572 RB Street motor advice?

Biomedtechguy said
Hey, I am on FBBO 95% of the time, 70 V-code Roadrunner w/a 71 block with 6bbl rods and crank, 292°/.509 cam, 2⅞" TTi headers, manual transmission, Dana 60, yada yada..
I'm having Southeastern Performance do a 572 build for me, with similar intentions regarding use. Local car shows, out of town "Mopar Events" when I can make it, and those incorporate race track time and show&shine. I will be going to my local track Wednesday night for Test and Tune which means I can line up some races, and I have a few friends who bring their "other brand" cars. Cruisin the Coast is a guaranteed event I go to for a whole week each year, and I was concerned about a solid roller cam and lifters because of the long stretches of traffic idling. My manual transmission may help keep the RPMs up a bit in traffic, but I didn't want to idle any higher than absolutely needed, and I got EDM oiling design lifters, so I'm not going to sweat it.
I considered the 572-13 heads, but I bought TrickFlow 270's. I'm having an Indy ModMan intake CNC'd for Max Wedge port size and using my Promax modded Holley 6bbl carbs. IF I find I want more flow than they can offer, F&B 3x2 EFI/DPI fuel injection would be my next move. I want to stay low profile to keep my N96 hood.
Here's my cam card, BUT the T&D rocker arms from B3E Racing Engines with the valvetrain geometry correction kit are 1.6 ratio, not 1.5, so lift will be about .665 and the TF 270s are the top option for up to .700 lift, solid roller.

Biomedtechguy, I see we think alike. As you can see this thread is old. To update, I took the plunge and bought B1 original head package with Stage 3 porting, T&D rockers, etc. It took 10 months to get them (Covid-Supply Chain). Engine shop was hit with Covid and dropped the ball on pistons, took 12 months to get them. My stepson passed from Covid in July 2021 and my son passed from it in December 2021. All of this has setback my plans. Currently engine is in pieces at engine shop. I ordered a Comp Cams solid roller XR286R, 286/292 Duration, .576/.582 Lift which should get me close to what I'm hoping for? I gave up the cross ram, going big dominator, or Holley Stealth kit. Car is in line to go to top level chassis shop for back half, 4 link, and full cage with swing outs. Car will handle the motor. Hope to get it to gather by Spring? In retrospect, I wish I had gone Gen II Hemi. Issues like parts availability, spark plug access, intake options, etc. To far down the road now!
