Im looking to fill the water jackets on aluminum heads for a alcohol boosted application and looked at numerous pourable epoxies. What is the best epoxy for this application?

Im going to run the Q-16 this year in my turbo charged Olds. I hate to go into this blind as parts dont come easy for the Olds. Ive been told to fatten the map up by 6%, Im currently seeing air fuel ratios 11.2-11.4 with 23* timing. All this is with the C-16 .
