Hello again,
I've used search function but i didnt find what i wanted to know

SO,
Im going to make this swap,soon,i hope,so i have few questions

H23 body is made for around 6500 rpm and when i put Vtec Head i wanna make 8000 rpm without overloading the engine.What should i change to make this engine more resistent for high rpm?
New pistons and rings,valves and retainers,camshafts+pro gears or anything else? I know H23 doesnt have "piston oilers" which h22 has,what would you recommend,to use it or not after swaped h22 in h23.
ps. i dont want to do full h22 swap...
