    vortec heads and roller rockers

    so the l05 heads are killing me and its time to upgrade to a set of vortecs.

    since im going to be doing heads and intake i might as well do some 1.6 roller rockers as well right.

    so im looking for some suggestions on brands of rockers. main concerns are that its stays fairly cheep under 250ish. and be dependable enough for DD status seeing as how i drive my truck as much as possible weather permitting

    thanks

    im doing the exact same thing you are next season. If i remember right the spring seats are gonna need cut with that much lift.

    No help on brand. I know the comp ones are good but hella expensive im sure.

    i ask b/c this makes a difference......i just did mine and they are center bolt, self aligning and i used the crane narrow body self aligning...they cost $$$ but, i found a set on ebay that a guy used for about 3 months and parted out his 350 b/c he wanted a big block for more power...saved me money

    None of those will work with centerbolt heads and if you have guide plates stick with a non self aligning rocker arm.
    Unfortunately to get quality roller rockers your gonna have to fork out around $300 for ones that fit centerbolt heads.

    i wasnt aware that vortecs could run guide plates. ill have to look into maybe doing a screw in stud conversion with guide plates

    well the whole point of roller rockers is reduced friction.

    so if i take a stock roller short block and add an lt1 cam and vortecs and roller rockers that would be a prety stout motor

    vortec heads are the best flow production head on the market. they even flow better then the 1996 vette/f body aluminum heads.

    (iron vortecs are based off the caprice iron lt1 head aluminum lt1 heads are based off the iron caprice head as well but gm had the iron vortecs in development for longer so they got more tweaking)

    regular vortecs or fast burn? fast burns from what i seen are worth the money. suprisingly i've put a set on a L69 305 with a stout cam that made a liveable 390 hp.

    vortecs are fast burns

    they have a fast burn chamber.

    i thought all vortecs were center bolt........but yes you can drill and tap your heads for guide plates and use non self-aligning rockers.............you have to drill the heads anyway to enlarge the pushrod holes......they need to be drilled one drill bit size bigger, because the 1.6s move the push rods in a bit so you have to clearence them............and the vortecs just aren't aluminum, that is the only difference between the fast burn and the stock vortecs

    and while you have the heads off....i got mine cleaned and re-vavled....when i filled the intake and exhaust ports with water(on a bench, not on the motor) i found that i had 1 exhaust and 2 intake valves leaking.....and i had a set of LS1 heavy duty valve springs put on makes my valve lift good to .600, shich i most likely will not get to............but the 1.6s will about max out the stock valve springs....so if a cam is in the future which is sounds like it is...put some better springs on there while it is apart....

    sorry for the short book...i just did the 1.6s so i have a lot of input right now
