I am running a yellow clone with billet .020 over rod flat top piston, raceseng s2 finless flywheel, black mamba cam, clone head that's been milled .040 with 28/25 as valves, raceseng 1.3 roller rockers, 26lb springs, stock crank, filly 304wx dominator on alky with 32 degrees timing and loop header. Do I need heavier springs? Are billet lifters and chrome moly push rods a must? If so what lengths? Any other suggestions? If I forgot any details needed on the motor let me know. We run on a track that's between 1/9th and 1/10th mile. Thanks
