EQ Heads and stock rocker arms?

I installed some .028s in my 367. I don't recall what manufacturer.
At the end of the summer, at my usual tear down for inspection, I found both sides were getting ready to pop, between the center two cylinders. My compression ratio was 11.3/1
I replaced them with the FellPro .039compressed, and remachined the decks for 10.9Scr and never had a problem with those. In fact they have been reused several times since then, and have now been in there since about 2004.
I wanna say those .028s were Orange, but I can't say that with conviction. They mightabin black. I took that engine in and out 5 winters in a row. All or most all of the gaskets were re-useables, and I figured it was better for me to pull the engine and inspect it, then to replace it if it blew up, cuz I had no money to do that twice. And each winter I caught a different issue just in the nick of time. But the last time, it was A-OK so it stayed in since then.
