Are there flow numbers out there for a 194 head with stock valves and lumps?
Trying to glean what I can from different places as to increase percentages that might be gained by adding lumps. I've read around 10% to 15%. That could move the 194 to a possible 187 to 196 cfm without any other work. Tom got about 24% on an open chamber head with 1.84" intakes, lumps, and porting. This is at .50" lift.
