But of course.
One would need to skim the block instead.
Not sure how much gap there is between the piston crown and the top of the bore at TDC. though...

In Theory it should be the thickness of the gasket. When tuning the old Pintos used to over bore and deck block the machine a relief in edge of piston crown to allow piston to use head gasket thickness

Hi all
A further question and an admin query for you.

were the o series ever adapted for unleaded or will have have to use an additive in the fuel?

I have tried to reply to a couple of private messages off the back of this thread, but my responses get held in my outbox. I'm not sure what i'm doing wrong but any help would be appreciated

Thanks

Mike

The O series is an aluminium head and is already designed to use unleaded from the start.

No worries.

If they are still in the outbox, that usually means the recipient hasn't read the message.
