Intro to a port job

Interesting thread. :) Im away to start porting a set of 587's that have been taken out from 1.88" to 2.02". They where fresh when I bought them, maybe 300 miles or something. Wish I was able to flow them though, would be amazing to see the progress on them.

There is a thread called "360 head trip"
360 head trip
It gives before numbers w/1.88 int valve and after some porting. Think they went 241cfm iirr. I'll fwiw flow one port before, I'm not gonna waste too much time flowing all of them before to find the highest, just one random on each head to show before and any variance. I WILL flow them all in the porting stage.
