Alright guys, I need some expert advice here. What will the impact be of switching to a 11:1 piston in my F22B1? Are stock rods safe for this compression ratio? Will I run into detonation problems (even if I run a colder plug and 93 octane)? What other considerations are there when jumping up so much in compression? I really need some of you all-motor guys to respond with some sound advice.

I have had a 3-angle valve job, port and polish and intake manifold port matching on the top half. Also milled .008 (to make it flat again after a blown head gasket).

Thanks for any direction you can provide.
