a 292 duration cam should be around 240@ 050, but LSA/LCA are still very important, this is a decent amount of duration on a 350 and yes it is possible that the vic jr would work better, you'll just be bringing the powerband up some with the single plane, i would still be very cautious about the 015 head gasket, without machine work going from a 040 gasket to a 015 is a little crazy (if the quench was set up right to begin with)

if your quench was around 040 to begin with and now they have lowered it to 025 just to get a little cr out of it, that is stupid!, optimum quench is 035-044 you can go as high as 060 but i wouldn't, the smart thing would not have been to put a 015 gasket on but to never have bought the 76cc s/r's

i would also be a little concerned about the cr with the cam chosen, but as i dont know the rest of the specs im not for sure i know the 292H comps cam want about a 10.0:1 cr, and you dont need a 750 to run this at the track, a 350 that will only rev to about 62-6400rpm will only need a 650, if you plan on hitting 7k i would advise a good 750 but you would still be fine with a 650
