They have been CNC'd like yours but 2.08" / 1.575" valves... plus the 4" stroke...a lot of torque which I love in such a heavy car
Kooks makes an 1-7/8"-2" stepped header...that may be my next move and swp out the 1-3/4" Kooks I have now

Again you have one stout ride for a stock cubes and production heads...sleeper for sure
DuSpeed hands down my favorite change...

Great numbers. Did your Fast 102 come black or did you paint it yourself?

Thanks! I have 2.05/1.575 valves in mine


Tony painted it when he did the porting to the manifold.

Came out AMAZING! His work is very meticulous and he knows how to make some power!

Looks amazing, well done to both you and Tony

An intake ported by Tony Mamo

Great numbers by the way OP. I have the exact intake waiting to go on my 408. I'm hoping for that 45ftlb increase that you found!

Good results! That thing picked up right @ 50hp in the 5300 range. Awesome gain!

Not surprised you gain that much over a stock ls2 intake. Congrats!!

AZGTO

I'm sure you will see big gains too, he does great work and the Mamo Fast works wonders

I guess I didn't look at the chart and compare it that closely, but damn some nice gains through the mid range I gained as well!

As said above, Tony Mamo ported intake

Thanks!
