I don't think they knew what 'stage' your cam was either. Isn't your car the one that had the valve guides all screwed up? I think your car is the closest one we have to compare company 'A' product with company 'L' product, no? Has anything else been changed that might skew performance numbers? I want to be fair here.

What ever head flows more@.300 and .400 with the smallest intake runner is the head you want. I know people with really high nuimbers but I know for a fact I make wayyy wayy more power with a smaller head. I don't know the specifics of why but I know.

Lol how many hundreds of LE vs Ai posts have there been? And now numbers show a back to back comparison (as close as this board will likely ever get) with an obvious "winner."
Good to see some results.

congrats on the AI setup! They really have their stuff together. Hell, two springs ago they only offered the 190cc intake port on stock castings, and that is what I bought, and I am at 438rwhp, but that is with a 385 bottom end.
That accomplishment on a stock bottom end with that many miles, WOW! That is awesome.
Wonder what those heads could do for me...

somewhere where LE removes some huge amount of weight from an intake
when it's ported. Did you happen to weigh the stock vs. ported intakes?
I noticed that the work done on my intake is very subtle with the main effort
opening the front up for a 58mm TB, and of course any milling to match the
heads for proper sealing.

I will let you on in a secret...but don't tell anyone

I suspect the OP heads are a tad smaller than the heads they replaced

Now you've got me thinking regarding the stock intake. I remember a post

~18cc's to be exact.

a little bigger cam and a little smaller chamber and you easily get the results shown here. i am in no way advocating anyone just think if everyone is gonna judge the facts should be straight
