Ok, but about a well (ab)used (150K+ miles), stock LS1 pump??
Would it be worth it to replace that to stave off future; wear/failure/problems just due to mileage while one was already in there replacing the timing set anyway with a 'low cost factory upgrade' LS2 single roller timing set??
I was looking at the Scoggins-Dickey graphite coated deal, the Katech one (pretty much the GM factory racing builder), and the Schumann Motorsports Sportsman unit with the ballcheck valve, ALL stock oil pressure, but supposedly slightly higher volume.
