The cost is not that high, we have about a grand in ours not counting man hours. The man hours is what drives the price up. We ground on ours for about a week. We will have dyno results soon.
 
I think the main thing is to open up the air flow to the 2 end cylinders. I have burnt pistons on both ends of my motor. Who knows how much the porting will gain? I should have my truck back together this month and am anxious to see what difference it is going to make . I will be running the same setup as in the past to check it. I am also working on a 12 valve manifold now and should be done in a week or so .
 
Stupid question perhaps but wouldn't an intake (for the 12v atleast) like the banks with two feeds into the plenum help solve the air to the 1 and 6 cylinders? I've not paid much attention to the cylinder head thus far but is there some "bigger then cylinders 5-2 restriction" in cylinders 1 and 6?
 
So with having the intake cut off. And have individual runners for you intake to one big plenum at the top. Where does everyone prefer the air to enter. Straight through the front by cylinder number one?? Or through the top with 1 or 2 openings???
 
MAXTORQ built my engine with his custom steel intake. Aluminum intakes will crack under high boost. The head was ported by him and then was shipped off to EXtrude Hone who ported even more and smoothed everything out real nice. Now with 3.54 gears and running 70mph on the highway I pull just hair over 5psi boost with twins. On the dyno with a 500hp run and spinning the tires on the rollers the boost was only 55psi and EGT's never got above 1150* with 10% load on the dyno. IMO the intake and porting the head is worth it. Even with 5x18 injectors and 13mm CDS p7100 I can get 22-23mpg on the highway. I have zero EGT problems. Engine breaths much better than when stock.$.02
