Cannot answer the question with certainty. I'd guess that you would be alright.

What pistons are those? Any shelf piston for a 440 w/o valve notches purchased in the last 20 years will have a 1.99" CH, or less, add in a .040" gasket and a valve grind or two, probably okay. Kinda curious what your cylinder pressure is, or do you know how far in the hole they are?

Of course, the duration is the number that matters more.
