bro wanna play this engine..just keep it basic..invest more on long term stuff for the car...such as suspension, brakes etc...things can be sued when you do an major engine upgrade or engine swap... for the engine..you got ur exh setup covered alr ...what ever changes you make from here wont make much difference.
since you like more top.. you can opt for a adjustable cam gears, and set your cam for power up top.get an emanage or any piggy back and get the car tuned... can suggest to do more...but in the end you if gonna change engine , bettere not spend too much on stuff you cant reuse... like semi racing cluth, port and polish and skim the head... etc2... thats why focus on the car handling and/or braking.. things that can maintain when upgrade engine. piggy back can reuse... but must retune next time if you change engine or upgrade bot.
