Help with 360, too much comp?

Ok long story but I had a 360, .060 built with x heads, KB pistons kb190, comp 20-671-4 (.484/.484, 284/.291 duration), airgap intake, stock crank, everything has been balanced.

Now I came across some Edelrbrock 6077 360 heads I want to put on it, I am worried that It will be too high of compression. From the numbers I have ran for possible compression ratios, it looks like ill be close to 11.5:1, how streetable is that? Motor is going in a street car, I run 93/94 octane all the time anyway and know the aluminum heads will hold little more comp. Cars going to be taking a long 6 hr drive plus a ton of other drving this year. Also Im in ohio if that matters at all.

Also I bolted the eddie heads down without a head gasket and pistons hit, put a .038 head gasket on and they dont. I dont have the correct tools right now to measure how far piston pops out exactly. I am getting edelbrock head gaskets that are .050 compressed to help a little too. Please any advice would be great, I dont want to buy new pistons and I want to use the eddie heads.
