ported j heads

moper, i had to do some digging but i came up with my cam card. lobe seperation is 105 recomended @ 103. intake duration @ .050 is 264 exhaust is 272. 294 / 305. .567 intake lift and .578 exhaust lift with a lash of .018 and .020. with cam in at 106 i have got 205lbs of cranking compression. when i had it in at 103 i had 225-230lbs but it hit the tires so hard running high 7.20s @93.45 mph with only a 1.60 60'. our track didnt open back up. then i retarded it to 106 went to a another track and my 60' times came down from 1.60 - low 1.50s and ran 7.19 @94.5 mph leaving @ 6600 and a best of 7.17 @ 95 mph leaving @ 6800 with a 1.50 even 60'. our track was a heads up racing track lbs/ci. it has closed so now i have to drive further to a another track that is a bracket racing track. but seems to hook harder. should i put the cam back in @ 103 and leave the spring pressure where it is @ 135 seat and 350 open and try it? i do have a set of closed chambered w2s for a flat top motor but would like to see this car run a 7.00 with j heads am i crazy? thanks for any help. i have not had it on a dyno guessing 425-450 hp!
