Hmmm...
I have a Weiand on 2511. The opening in the block, the hole the thermostat 'hat' closes off, is filled with an epoxy of some sort. I assume the Weiand is not drilled for bypass function. I am running a high flow Windsor thermostat.
My Pantera has somehow managed to survive just fine for the last 33,000 miles in this manner.
Moral?
YMMV
