Offset gudgeon pin on 3.5 pistons

Hi, I haven't posted on here for a while but having started a rebuild of my 3.5 i have a question. I've got some new HC pistons and and I've noticed that they have their gudgeon pins offset by about 1.5mm. I thought it was only the 4.2's that had this and that it was only 0.5mm.

Has anyone else used these and are they better than standard pistons with central gudgeon pins? I assume they're OK to use.

Thanks

That's a new one on me.
And which way round do they go!

I know why some have an offset and which way round they go (the offset goes towards the thrust side of the cylinder), I've just not come across it on any other set of pistons for the Rover V8 (other than the 4.2).

Maybe it’s cos they are HC.
