What head gaskets are you running?
Maybe 10 deg duration bigger cam with thicker gaskets.
Seems like many people push higher compression setups. It's easy HP, but not realistic with 91 octane pump gas.
And people think/say they are running higher compression than they really are. Some like to brag and bench race inflating their compression numbers.
I'm 9.7-9.6:1 measured with 242 @0.050 and on edge with pinging.
