Make sure you check piston to valve clearance. Should be a fun ride when done

of course i will check ptv clearance hoping i will not have to fly cut as speed inc told me it will not be necessary with stock heads which is the only reason i went this big

I had a hair milled off mine at the time and ran a 238/242 when I pulled the motor down to go bigger there were marks on the pistons where the valves just touched a few times...I got lucky and didnt do any damage

With that cam I would run a 4K stall to maximize performance.
