Yes sir
Yes sir
Did you do any chamber work to go along with those larger valves?
See the chart on page 1. I think the cnc head is there.PHR, so can we assume an untouched CNCed head would flow 250 or so? Thanks. Kim

The “OOTB” test(coulumn A) is just as it came ootb.
That is the CNC ported head.
The OOTB unported head is in the 250 range(on my bench).
Really sweet heads.
Do you know in what bore size the head tested at?Got my w5s back today, was hoping for better flow numbers.
They sure are pretty! It's fun to look down the intake ports and not have to look past the pushrod pinch!Do you know in what bore size the head tested at?
Was there any mention of the port going turbulent?
Did the head require epoxy?
Did you mention your valve sizes?
I wouldn’t be to upset. That’s enough flow right there for some serious HP. Plus the head ports are still moving some pretty good air past the peak. If you were so inclined to continue lifting the valve, you will still be making more power.
The only 2 drawbacks to the W5 head is the possible poor casting ether turning the head into water sprinklers (leaking) and/or not being able to be ported out to some of the reported superb flow numbers that have been done. Then the expensive rocker arm set up even though it is seriously superior to other offerings, which has excellent dividends, it’s just pricey as I said. Though if it is a race car, it would be worth it. Street car? Ehhhh, owner’s call.
Again, I understand being disappointed with the flow results but they show well enough for some *** kickin.
I agree and that’s what makes these heads (W2/5) worth it. A larger unobstructed port window (Or a door to allow more people in) than the LA head and it’s replacements.They sure are pretty! It's fun to look down the intake ports and not have to look past the pushrod pinch!
Choose the cam wisely, the exhaust is frisky .100-.300ish ,watch the overlap.
