318 head porting for the average joe
yes, nothing other than smoothed angles/casting flash just above the seat and nothing else
For those who cant wait...lol...i have already done one intake port and exhaust port that flow over 210cfm int/145cfm exh cfm w/1.78 factory valves and valve job.
If you knock out the guide it picks up quite a bit, lay the turn and go to about a '90% of seat' bowl and it really jumps.
the exhaust is easy on these, they have a good floor and all you have to do is raise the roof/knock out the kinks in it and round/enlarge the bowl...and bam u shoot from 118/120cfm...to 145-150cfm w/ 1.50 valve
When im done working today I will continue on, but for now heres the exhaust pics as cast vs one I did 6 months ago that flows the 145 cfm 'stock 340 exh flow numbers w/1.60'
The worked port is rusty, sorry bout that...i did it 6 months ago and it sat outside....when i get home ill toss it in the blast cab and then post the new cleaner pics. this is just till then..
