On the fast road pistons 11.2:1 the valve cut outs are larger on the exhaust side where i thought they should be bigger on the inlet side due to larger valves ?

Anyone got a pic as its clear when you see them.

Got a pic somewhere....
Are you sure you have them the correct way round?

Check which way arrows are pointing.

I have the same pistons and they can take up to 36mm valves (I have exactfigure in one of the emails from Wossner). Anyway, I have 34mm inlets and cams and it's fine. So there's nothing to worry about.

The arrows should always point North ;)

Yes, but don't forget to correct for magnetic declination or your engine might sieze! :lol:

arrows for some reason point towards the back of the block iirc

If thats the case then K-tec have built a bottom end with the pistons the wrong way round..!!!

and that surprises you??????? lmao

noticed this many moons ago when i built my first one...they are arrowed back to front against most other makes.

the omegas etc in the minis back in the day were always pointing the opposite way round to the clios.
