Okay, a short while ago I was hoping to get a XR6 head, cam and such. My mate reckons that you need 'XR6 pistons' because the XR cam would cuase the valves to hit the pistons...

My mate I mentioned above thinks the stock XR6 cams are something insane.. By the way the models we're talking about the the early E series, just in case the latter XR's have something with a larger cam than the E's do.

So, can you guys help settle this? Cheers Luke.

lol, there is no need for different pistons.

Cheers, lets see him say that you're wrong too
