One caution:
If your current band saw configuration has any vibration during start up/shut down, or when running due upper wheel balance, worn bushings/bearings, slop in tension spring assembly; the riser block will amplify the vibration.

+1 on saw blade width limitations, and required horsepower for re-saw greater than 6”.
Even with a 1.5HP motor on my 14” Delta with riser block, it is not fast cutting thick stock.

+1 If you intend to re-saw more than a few times per year, will be much happier buying a larger 2-3HP band saw intended for the job.

FWIW – I’ve owned an antique Delta, and white painted Taiwanese clone 14” band saw(s); adding riser block did NOT make either a better saw. Both of these saws passed the ‘standing nickel’ test without riser, but only Delta could pass with riser added (unless near max tension for 3/4” blade, then it would fail also, IE stuck using only 1/2” blades).
IMHO – there is too much flex with cast iron frame and cast aluminum upper pivot mechanisms on most late model 14” band saws to make adding a riser viable long term: even with larger motor, new ball bearing guides, and Carter spring package; especially if goal is 3/4” wide blades.
Do not get me wrong, my 14” Delta with riser slices a 1/2” blade thru 10” lumber very well, simply requires patience and some extra effort to keep equipment properly tuned.

Put another way > Been there, done riser block upgrade, got the T-Shirt, and Now I want a larger band saw! :)

Best Luck on your decision.
