Hello,

We're having a little debate on the MLR about the correct installation for 4b11 liners:

AMS have been quoted:

A few members and traders believe installing the liners proud of the block will stress the head and block and could cause problems.

I was hoping you could provide us with your feedback on this topic.

Many thanks in advance.

This is a quote from our engine builder here at AMS:

Yes this is correct that the liner is installed proud of the block deck. This is no different than having an o-ring proud of the deck or a gasket with a stopper ring built into it.

We have done this with all of the sleeved engines without failure or signs of fatigue to the block or head. I think our HP records, quarter mile records and road race records speak for the integrity of our motor program.
