What Epoxy for Aluminum heads

[bigtime]

I know not to many people use epoxy in ports anymore but i am in need of some.
I need to fill the floor of my SBC AFR heads about .400. The car is boosted with FI so they won't really be seeing fuelas the injector will be spraying right past the epoxy. I use C-16 when not running on pump gas.

I have read JB weld works and Devcon #10610.

What kind have you used and was it durable?

Thanks in advance, Bob
