is 11.2:1 compression too much for 91 Octane

Its all about the Dc/r, and the al heads suck some heat out, and timing, and loading, and engine temps, and driving style, and traction
FYI, I ran 11.2 with a 240*cam@ 195*F in my 360M/T and 3.55s @ 3650#with 325/50-15DRs. No issues.Never had a BB. Currently running 10.5 with a 230*cam @ 205*F.Not sure if it helps.Ran them both on 87E-10
