Looks too lean to me as well
It only kisses 13.0 to 1.00 one time
I'd bet it makes best WOT power somewhere between 12.5 to 12.75
I don't think LT's would give you all that much more WOT power over
shortys if you stay with the same tube size
Having said that ... maybe you need to step up in tube size
I'd not be suprised if you gained much by going to the Fox air intake
system setup
Honestly ... for NA ... I've yet to be convinced gains are there
About that spark
Of course ... I'd not know how he went about it ...but
If he added 10 and you had nothing pulling spark like act temps or the like ...
You'd think that would put you at 35 total spark
You might pick up some more power with more fuel and spark
but
That is just something you would have to try
I've seen combos with Aluminum heads make max power with spark as
high as 38 to 40 total but each combo is different for sure
I can say I make max power at 36 with 93 grade gas
I'd think some 1 3/4" LT's would help you more than a different air intake
system
I think Paul has a good idea about looking at your valvetrain for correct geom
and making sure your valves are not too tight or loose
