Stock plastic CIS injector blocks are prone to cracking and warping, even with standard 32mm bore and standard thickness walls.
The factory bored them to 36mm on some S/SE engines, and they failed sooner still.
Try to go larger, and the walls get really thin.
Somewhere in the shop we have a ported one that blew the side out at 1.0bar boost.

Thus aluminum injector blocks and thermal insulators. No more warping or cracking.
