The current version is using Apache heads, with 2.20X6 MM, 1.67 X 7 MM Del West titanium valves, surprisingly not as much port work as you might think, on the porters bench they hit 395cfm@ 700lift, on a popular "Hemi Specific builder's bench they hit 410CFM at same lift.
Most porting work is in the bowl area. intake ports have what is called a burr finish(rough, real rough)when I 1st saw them I thought WTF builder wrecked my heads...but he said , it'll hit my goal and it has., next step is Thitek , this 468 is at the end of the flow potential of the OEM heads, If I want to crack 2.0HP/CI with this thing I need another 50 CFM per port .....or I could lighten up this fat ass ram ....but I like the leather seats (LOL)
EDIT: you'll notice between the two WOT there is almost 6^ more between 3400-4500 RPMs then in the "track tune" with the street tune(@the track) I get too much wheel speed shifting into 2nd and it "shakes the tires"(wheel hop) I run a 727 trans in this truck, NO OD , I was running a 518(46RH) for a while then swapped over to a 518 NON-Lock up, because of poor convertor selection. when the previous owner built the truck he dumped the 545 ij favor of a T56 set up out of a wrecked 05 SRT ram.

Those are some really good cylinder heads. Many people are caught up in flow numbers but what about wet flow? That's where burr finished ports really shine.... Keeping the fuel and air from separating. You certainly have a "tuff" combination. Have to love all muscle horsepower!
