    Should i get the new SS grate?

    yes, if it is not too late

    Should i pitched the prop to a 14/22?

    yes

    Should i shaved the head a lil more n go with av gas?

    no

    add back the sound supresion box (this will raise rpms)
    get some R&D trim tabs, cut the back off (make them same length as stockers) and shim them down 2 washers under all 8 bolts
    get mounts of rideplate machined to increase angle

    first of all welcome to forum
    all the great guys are at the bug so you will have to put up with me
    your rpm's are too low to pitch up,between 7150-7250 is ideal ish for non pv
    no to av gas you may go slower..
    was the prop out the box...there off big time in some cases..
    you need to get your plate sorted to pick up some missing speed,
    i would guess with your mods if you cut plate and mess with tabs you should be aprox 75mph with ease...
    if you want to go fast and be safe get the ss grate for sure
    reinforce your tunnel (this is a must)

    philip whats he going to drop to rpm wise if he's spinning 14/20 @ 7110,thought that would be close to deto 7000 mark
