FS: Patriot 317's Hand Ported over CNC I have a set of stage 3 Patriot 317 casting that have the 2.02 intake valves and 1.60 exhaust valves. They have been hand ported over the top on the cnc job. They flow well into the 300's on the intake side on a SuperFlow600. They numbers seen low, but on TEA's bench or Patriots bench the numbers will be highers. I willpost pictures tonight also with some exact flow numbers. They are a really good set of heads, they just need vlave springs and seals. I will take $1000 plus shipping for them. Shipping shouldnt be too bad. Again these are not off the shelf heads. The chamber is 59cc. If anyone is interested in them let me know.
The flow numbers are as follows and are from a 3.900 bore.
int. exh.
.200 148 119
.250 180 141
.300 209 163
.400 249
.500 280 209
.550 289
.600 295 225
.650 300 236
.700 306 246
