Okay so we know now that the more angles help the airflow. Air doesn't know the diff between the angles or a radius when done in 15* increments, food for thought.
I kept them right at/about .055-.060 width.fwiw.
We also know a basically bone stock #163 318 smog head does 173 cfm on the intake. So there is a spread between head castings if 5-8cfm peak. I really like the floors in these heads, they are laid back like a 273 era casting, but with more meat under the seat 'so to speak'. I'd like work a way to get 200 without all the porting in was doing before with the 'bargain' 2 angle vj. Goal is to do just a lil straight side ssr work and then lay the vj onto it and end up with 200cfm..without profiling the guide would be nice.
