Anyone had their cylinder head ported 7 polished

[chris watton]

Just wondered if it's worth having the head ported and polished at some point:

I know that it makes quite a difference to the K-Series 4 pot, but what gains, if any, could be had from this for a S6?

Cheers.

What's the point if you're going to 4.3 next year???????????????

Go for it. Add approximately £1500 to that price to take your engine out remove the head and put the engine back.

I was merely curious, that's all.

I was thinking about the 4.3 - as the engine's out and apart anyway. I am assuming the upgrade doesn't include porting and flowing?

OP have you tried asking Power what the likely performance gain's might be (presumable will need at least a re-map to realise the potential, plus intake and exhaust mods, may more).

Perhaps Dom could reply on here and let us all know?

The head on the t350r race car is ported* (standard valves). To be honest I don't think it's made a blind bit of difference. I just did it because the head was off the engine anyway and I had an afternoon free ..

• by that I mean taking the rough edges off it without changing the shape of the port. Without access to a flow bench you shouldn't go hacking out metal where you don't need to ..
