We are going with 195 (I think).
Here are the flow numbers for his CNC Ported 185:
Lift:cfm-in:cfm-out
.100:69:59
.200:129:118
.300:188:153
.400:234:178
.500:269:189
.600:278:195
.700:281:210
.800:288:228
For his CNC Ported 205
.100:71:61
.200:142:124
.300:190:162
.400:252:200
.500:287:218
.600:300:225
.700:305:230
.800:309:235
So, I sort of infer that our flow numbers for a 195 and .550 lift would be
284:207
How's dat?

If the 195's as cast are simular to the 185 CNC then they will work fine. The mid lift is not as good as AFRs (no one is really) but this is a "GOOD" head. I'd still like to see a set. Without a flow bench a clean-up (if needed) is the best way to go.
"In head porting, what you don't do is sometimes more important than what you do do". Brutal
If I do Porting 101, you will know enough to understand what entailes a good head.
