    I do not like SE heads.
    I'd rather buy a set of heads and have work done to them
    But would like to find somebody that could keep the elec compression release in.

    How much they selling them for?? Se heads would flow better than stock but would still benefit from a "clean up"(smooth out casting ridges and such)...

    IMO you'd be better off getting your stock heads worked...

    Here's a price list from one of our members (prodrag1320)for you to compare cost of buying vs porting...

    Before you ever start jackin with a set of heads.
    YOu need to take to a Head man, know which cam you are gonna run and what you are lookn for your bike to do.
    Some cams run better with STOCK heads.
    There is a formula that they go by.
    There is a thing called Port Velocity that will tell you with a cam what kind of heads you want.
    Had a builder explain this to me years ago.
    I only remember parts of it.
    But he's only about 140 miles from me now.
    Where you at Red.:gah:

    COntact Kirby our member ProDrag, the link posted above
    Pull your heads and ship to him for some work while it's cold and
    bad roads over the winter up there.

    Also contact www.harleypartscheap.com and get
    a larger throttle body from Kuryakyn, won't help a ton
    if your heads flow 600 CFM and your intake only 450cfm.

    Then you need to tune that bad boy and there are three
    basic options

    1) ADD On Tuner: Power Commander 5 with Auto Tune (or not depending on map needed)
    contact jamie at DYNOJET POWER COMMANDER III USB they have maps done for most builds, it's a plug on solution meaning the PC will be on the bike with stock ECM.

    2) FULL ECM REPLACEMENT: Cardboard will drag you to zippers for the Thundermax with Autotune which is a complete ECM replacement, nice , expensive, works, but
    a complete ECM replacement.

    3) SOFTWARE SOLUTION: TTS Mastertune is a software solution, same as Tmax but
    it changes the map IN your ECM vs replacing the whole box or having a part you add onto the bike like the PC.

    All three work well, all three will get you good results, all three have different price points with the Tmax being the most expensive solution.

    Just pick one that fits your style of tuning.

    Woods has a new 222 out too that runs great for lower compression engines.

    ty ty ty ty very much. i have been lookin into the power commander auto tune i already have a pc 5. unaware of 450 input throttle body and 600 flow rate of t he s/e heads. very useful info makes sense. u guys r real fart smellers, i mean smart fellas. i guess the auto tune will sense r realize the exhaust output and adjust to accordingly. it wont have to know the head brand in particular. right? if i call for a custom map from dyna jet will they be able to adjust a map accordingly. the answer to the cost is the shop is running half price labor and 25% off s/e performance parts so i think that is a good deal.

    BTW those numbers were just examples of what can happen
    not the actual flow numbers of those parts.

    My point being that if you increase the capacity of the fill, and
    ability of heads to flow air, but the intake and filter won't flow enough
    to feed those heads then you really don't get any gain...

    A couple of numbers you might wanna watch is the cam specs for the Woods 555, (You got specs for them CB??) and combustion chamber size on the heads(got a part number for the ones you're thinking about?) If you have a short cam with early intake close that increases cranking pressure and small chambers on the heads that also increase pressure,you could wind up with a combo that pings,or is hard on the starter,or both...Gotta be a system and the parts work well together...:)

    Like I was saying for a stock bike, look at the 222

    Call Bob and ask the specs, He knows it from head to toe

    Yep...sure looks it,.030HG and she'd pull like a mule...Similar to the Crane 300... A little head work would boost the 555 too...

    :D Then again, a little head work is always nice...hehehe;)

    Have a head man match the heads to your build. You don't just throw a set of heads on a bike. And you don't just go for the biggest set of heads you find either.
    The port velocity should match the build so the cam can run right.
    Vtee performance could tell you about that.
