For an 8ft lintel. Is it ok to use a pad block that will need to be 6" long mounted on the inner leaf of an exterior double leaf wall? ...so the pad block will protrude a couple of inches from the wall.
Thanks.

not sure what you are trying to acheive here but...it's better to have the padstone sitting squarely on the masonry - any overhang, in this case 33% of the padstone, can destabilise the whole thing.
Why is the lintel only going on the inside skin? - what's holding up the exterior masonry?
Why not use a 3ft 4X3 pre-stressed concrete lintel cut in half, so that you have a 18 inch long, 3 inch tick and four inch wide padstone at each end?
having a 50mm ovberhang is going to cause problems, not least for the plasterer!!
It also means cables can not be routed over it - assuming it is in the
150mm Ceiling Zone.Without the 150mm Ceiling Zone you have to drop cables down the Corner
150mm Zone, run across the wall in a Horizontal Zone created by 1G 2G backbox with blank plate, then back up into the 150mm Corner Zone.Something to bear in mind re impact on other services... :-)
If I make the pad stone say 6" thick and it tapers from the 6" length down to 4", would that be a goer?
The wall is double brick (old terraced house) but a stone lintel which is about 8" high overlaps the the point where the back wall and wall to be removed, join. If I wanted to install the wall opening lintel above the stone lintel the job would become too messy.
It's a price worth paying to achieve a flat wall finish.
Thanks.
