    which heads setup is better?

    an LS1 with 5.3L heads
    an LS1 with 6.0L heads
    an LQ4 with 5.3L heads
    or a LQ4 stock

    keep in mind the heads will have work done on them

    thanks for the help

    I dont knw for sure but in my case, I made an impressive number with worked 5.3 heads with 2.02 1.57 valves and milled .020. It will be even more with the Fast intake and new lifters

    1993 Gmc 02 ls1 Circle D 3400 stall, long tubes, 220/224 cam stage 3 heads, weiand intake, auburn posi, 389rwhp 352ft/lbs

    cause ima old school guy..love the classics
    i originally was gonna do a carb setup..but did some research and saw that i could use the intake, but still be EFI

    that and i wanted to be different..almost everyone goes with a modern faster flowing manifold...with a ricer intake tube

    i want open element filter

    its mainly cuz its way ezer to tune man there was one guy on hear with a z71 6.0 with that set up and he liked it but dare to be dif i guess just do your searching on how hard it is to tune and the reason we use tubes is to get alot more cold air

    an LS1 with 5.3L heads= N20
    an LS1 with 6.0L heads = FI
    an LQ4 with 5.3L heads = N20
    or a LQ4 stock = Milled

    Why not go with an LQ4 with 241 heads? for the money they are just as good as 243s just upgrade to bigger valves and P & P them
