Head Help

Look up BJRracing here. He ports heads for a living and races.

But with the 1.6, the build you mention requiring a full porting for the flow numbers listed sounds about right. I think your on track.

The only thing I myself would do is step up in tube size. 1-3/4. Fitment may be an issue. On my E-body, the Hooker super comps fit inside without a problem save the Lakewood bellhousing issue and denting needed. If it was a stock bell, there would be no problem.
