Will these heads work OK for FI? 317 casting
hand ported
decked, 70 cc chamber
240 cc intake runners
80 cc exhaust runners
2.02" intake valve / 1.60" exhaust valve.
Flow Data:
Lift Intake Exhaust
.100 69 51
.200 152 99
.300 212 132
.400 258 156
.500 290 180
.600 302 191
.700 318 200
Tested with 4.030" bore @ 28" H2O
Planning to go on a stock short block, twin turbo.
I'm pretty new to the FI world. These seem like too much head for a N/A 346 to me, just wondering if they'll be ok for a FI motor.
TIA,
Craig

Craig ya gunna do it on a stock bottom end huh.....
Id look for another set of 6.0L (317casting) heads. either the stock 71.03cc chamber or opened up a little to 72cc's.... that will put you around 9.7-9.6:1 Comp.
What ya have in mind for FI
Shoot me a PM
