What kind of flow #s on your heads? Im shooting for 500 HP/TQ

.100" 67
.200" 127
.300" 187
.350" 220
.400" 241
.450" 268
.500" 285
.550" 296
.600" 298
.650" 299
.700" 300

Those numbers are with 2.055 valves. Brian at IMM Engines can get you just as good with a set of RHS heads for quite a bit less than I paid.
