Here's a photo of the 1UZ head with the flow figures written on it.

Do you have any more details on what mods have been done and what the curve looks like?

Also what lift ?

No the photo came from Auto Speed (I hope I don't get banned) and it was in an article just showing what a flow bench can do. I don't believe the other cylinders were done.

My heads are off at the porters at the moment and I'll be interested in what they flow.

Rod,

Make sure you do before and after data....

David,

They've started already so a little late to get before figures.

The photo shows the stock head's flow on the left.

I'm thinking of having some ceramic coating done to the piston crowns, combustion chambers, valves, inlet and exhaust manifolds.

I'm also looking into Phenolic spacers between the head and inlet manifold to try and keep the charge air as cool as I can get it.

What were the test pressures for these flow numbers?

[Zuffen]

I'm pretty sure it was 28" mg.

I'm pretty sure it was 28" mg.

28" mg? Do you mean 28" of H20?

28 inches of magnesium might be hard to keep liquid for a flowbench test! :approve:
