My 351 is starting to come together. It is 9.5 to 1 compression and will have nitrous immediately since the car already has it installed but will soon be a turbo car ( 2 to 3 months ) imy heads are on the way and are procomp 210s. I miss placed the flow numbers but if I recall correctly the flow close to the afr185s. Would you guys have them ported before put on or just leave it be? Oh yeah intake is the trick flow r unless some one buys it from me and I get the spyder intake with a 90 elbow. Tia
