My advice would be to educate yourself first by speaking to the clutch mfg. tech support teams in hopes of finding a knowledgeable person who can help you select the right clutch for your engine characteristics , intended use, and the TKX transmission.
In my low rpm big block application with a TKO 600 I’m happy with my McLeod clutch which is a street -strip style and does have a little chatter at low rpm street driving due to the dual friction materials I selected. It’s also a heavy clutch pedal to manage the 450hp and 450 lb-ft from my BB 460 using a HTOB. I can’t predict the clutch life for my street driven Big Block, but it’s been flawless in 7,000 miles of street use so far. But I drive it gently on the street. Back in early 2000’s when choosing my clutch I learned a ton speaking to Centerforce, McLeod and Summit tech lines. Opinion: From my OEM days I’m a big fan of the quality and durability of SACHs clutches if you can find one for your application. SACHs clutches deliver to OEMs for millions of cars annually globally and may have a performance high quality clutch for your application.

The twin disc clutch technology has advanced a lot in the last 10 years and should also be investigated for your application since the clutch pedal forces are typically lower if set up correctly with a nice HTOB. It comes down to how much power and torque you’ve set up your drivetrain to handle.and where your weak link is. My weak link are the 9 inch OEM Ford axles.which will break before the rest of the driveline given the sticky tires I use.
