I have pics of them side by side an the 862 ports are a good bit larger. I can't get the pics to post up. heres the specs ported 5.3 heads PRC 660lift springs, ferrea 2.02 intake and 1.57 exh valves, titanium retainers, multi angle valve job.. milled .030/ now have a 58cc combustion chanber. Guess this woulda been smart to have at the start lol.

IF the 862 ports are larger, they have been ported or someone attempted to port them. You can hurt flow very easily as material has to be removed in the right areas and if the port volume is too big then the velocity will be poor.
The best thing you could do would be sell them, and buy some 243's to be honest.
