182 manifold on a Williams. Will it fit?

[scuba45]

Has anyone fitted a 182 exhaust manifold on a f7R Williams engine?
If so what difference does it make to power and torque?

They don't fit, the flange to the cylinder head is completely different so it needs swapping over.
There's a thread on here somewhere with pics of it done with a 172 manifold, the other issue is making sure it clears the starter motor but not foul the bulkhead.
I reckon the solution to that is fitting a 172 starter but I haven't had chance to try that on an engine yet

That’s great thanks.
Looks like an exhaust manifold change makes a big difference to power and torque from that thread.
