I didn't know what I was doing in around the valve area & was cautious about going too deep & ruining a head. I did smooth off the surfaces that I could get to. I probably didn't accomplish much beyond matching the ports & opening & smoothing that interface area.
The Edelbrock manifold was a disappointment & I called their factory rep back then, he said something about mold shift, or something like that. I ground on the ports & straightened them out & smoothed out the sharp edges.
I wonder if there is a machine shop within 300 miles of me (I-25 & Colorado/New Mexico state lines) that could do a good porting job on my heads, at a reasonable price? Maybe in Denver?
I don't know what those rear suspension parts are, but I want to learn.
Where might I read up on them? Does Summit or Jegs sell them?
