But anyways, here's what the stock heads are doing

"Intake
.200 188
.300 255
.400 275
.450 281
.500 284

Exhaust
.200 135
.300 152
.400 160
.450 162
.500 164

flowed at 28" of h2o on a sf-600
After .500" lift they started to level out I still haven't decided what valve job cutter I want to use yet, I may use a little shallower seat angle but I may leave it a 45 degree seat." And don't forget these are port matched to the BBK long tubes that Phastek had as a pre-production set for testing.

Here's some of the V8 #'s he's pulled from the heads he's worked depending on the shortblock setup such as displacement and compression ratio....hope we can see similar flow rates, atleast up to .5-.6" as the stock cams only open up that far on the V6 heads. I wish I had some stock V8 SS flowrates to compare to instead.

Intake Exhaust
.200" 158 .200" 117
.300" 236 .300" 183
.400" 294 .400" 226
.500" 346 .500" 241
.600" 361 .600" 250
.700" 378 .700" 255

Intake Exhaust
.200" 162 .200" 118
.300" 249 .300" 180
.400" 306 .400" 222
.500" 339 .500" 239
.600" 355 .600" 246
.700" 363 .700" 251

Does your wife know what you're doing to her car?
