Did you not see the link I posted? Raw facts from the dyno. Try another one.
Keeping the LS rods (preferable forged since these are weakpoints of the LS motor) and using VTEC pistons would keep the same stroke, while using pistons that were designed to handle the higher redline. Like you said, its hit or miss. VTEC pistons are more suitable for such applications if Forged internals are not in the budget.
Pistons have nothing to do with redline. Are you really this stupid?
I agree, no doubt. However (once again), budget is what drives my argument behind the VAFC. Its cheap, and it does a half decent job at tuning. If in the budget, a better option would be to convert to OBD1 and run Hondata. However in some states (in PA for example) you cannot convert a newer chassis to an older computer setup. My Integra came OBD2, and for it to pass inspection, it has to stay OBD2.
That's how it is in every state that has emissions testing. We have it much worse in CA than you do in PA.

I've never seen an LSVTEC with a B16 head make more power than a GSR head, with the same bottom end. I've never seen a GSR motor with a B16 head make more power than a stock GSR. I don't know where you get your info from in PA, but in CA we have quite a few reputable engine builders and tuners that have disproved your theory. Just in case you don't know how to click a link in a post body, here's the dyno graph:
Blue = GSR head
Red = B16 head
here's the text from the article:
"This is a VERY good comparison to look at...
Question: What is the best head to put on my LS/VTEC, GS-R or B16A?
Answer: In the opinion of Atomic and myself, I have to go with a GS-R head.
Look at the graph...here is the 2 motors
On 1 side we have the LS/VTEC B16A head...coming in at 180 HP
The bottom end is EXACTLY the same as the GS-R LS/VTEC...exactly...
so it makes for a good comparison.
B16A has:
port flow port/polish (mild)
Civic Type-R intake cam
ITR exhaust cam
Comp valve springs/retainers
Type-R intake manifold
GS-R head has:
Stock head
Stock valvetrain
Stock intake manifold
ITR cams, intake and exhaust.
and it made a little more power, as you can see by chart.
With the GS-R head, you also will definitely get more torque.
For the money though, B16A head is a good choice.
Remember, this is not a perfect test, it just shows a pattern....

Now, Jeff is the owner/operator of ImportBuilders. He is regarded as one of the best engine builders on the west coast, and people from all over the country send their motors to him. So if you don't want to believe the raw data, or the opinion of someone like him, go right ahead and be dumb.
