Fast makes the biggest that i have found so far drop in injectors for 8.1 85 pounds. I am now in possesion of a raylar intake since my truck dynoed 430hp to the wheels with stock intake, stock tb, stock maf, and stock injectors. running at 122 % duty cycle at 5000. I will do a dyno comparsion of both my self made intake and raylars with everything else being equal and bigger injectors.
Also anyone bought any of the dart stuff?

I don't have any ported numbers on the new heads yet, but I did find the ported numbers from the stockers when I was at Innovation. Intake valve 2.250 ex 1.820
Lift..............CFM...............Exh.CFM
.2................157.................141
.3................230.................190
.4................292.................221
.5................330.................238
.6................348.................249
.65..............353.................251
These heads made 600hp(dummied down to 590) and ran on one of the bat boats in 06. They used the stock intake manifold and I believe a modified airvalve.
The iron eagles will flow more air with a 2.3 valve, very close to 400 cfm @ .700 lift

496 Dart Update
I have been thinking about upgrading the single 496 HO in my boat for next year and gave Tyler a call. He has a 496 new Dart head, cam, ECU package that puts out around 575hp n/a. I will let him chime in here on details if he so chooses.

I got a set of the Dart heads today ,Im not sure if it was a mistake yet .Im going to have them flowed , and a few changes,like valve size , compare it to Tylers cnc head.From the nakid eye I think I went backwards they dont have bronze guides, the spring seat is small,

Good for you man,that totally rocks! I would love to some real photos of those babies. Share any info you can please.
What is up with the shortblock you are putting them on?
