Intake Port Area (not volume) for LSX heads Can anyone tell me the intake port inlet area on popular LSX heads. LS7, L92, LS2, LS1 (5.3 & 5.7 if different). Also the runner length of the LS7, LS6 & LSX intakes would be great if it is readily available.
I would search for these answers, but no search

No one knows the cross sectional area of the intake inlet on any of these heads. I found something on the L92 head indicating it is 3.19"
Also found 16" runner length on LS6 intake.

The intake entrance area on the L92's is 3.166sq/in.
The LS7's are 3.152sq/in. The LS7 intake manifold runners are approx. 8.5" long. This is from reverse engineered data and not a factory blueprint.
The runner entrance for the cathedral heads is going to be misleading due to the injector notch in the roof area.
Sorry I don't have anymore info for you at the moment.

I posted some while ago pictures of stock LS6 intake runner mold.
Measured from it:
Runner entrance without injector notch 2.65"x1" (with out corner radius calculated off)
Then the runner starts to taper down when going to valve, but its a real pain to measure because of elliptic shape and swirl dam at the shortside, but intake venturi is ~2.38sq.in (1.74").
