Battling overheating new 360 build

Could be - I'm .030 over and also zero decked the block so my compression is up there as well. While I know I'm not detonating, I'm beginning to think I just have a hot running motor and need a more efficient cooling system. How hot do you run on average?

I would also suggest putting in a real temp gauge so you no exactly what you are running temp wise. Its a 40+ year old temp gauge after all.
