    It'll help with power, I am sure.

    Whether it's enough to balance out the (large) upfront cost as well as any long term durability issues - that's all in your department.

    Keep in mind, once you get in to that power range... a bullet proof engine just isn't bullet proof. The engine will probably break again down the road in a few years (sadly). At that point you may have some more cash around for the head work.

    You want to at least refresh the heads. I probably would skip doing the PnP to save money.

    I would do the cams (which require the springs and retainers).

    I'd keep the stock valves if they can be reused, or order stock replacements.

    PnP is relatively expensive for the gains compared to cams. The plus side to PnP is that you should see gains across the entire powerband. If you have to pick one, cams are more bang for the buck.


    Beehive springs are good because they are basically a progressive rate spring allowing for less loss of power compared to a stiff dual spring setup while still retaining the needed pressure at high revs.

    The beehive valve spring shape has become the buzz lately. Some have enquired as to the benefits of a beehive spring vs the dual springs that are sold by others. While some might find that the beehive spring design is new it has been used commonly in many OE engines as well as in all of the NASCAR and F1 engines of today. Why? The beehive shape is more stable than standard single or dual cylindrical springs. The beehive design which incorporates an ovate wire is more than capable of the performance demands that were previously only matched by a Dual Springs. With the smaller and lighter retainer used on the beehive valve spring allow for higher RPM and more valve control. So beehive valve springs, with there lighter weight retainers allow for engine's to rev quicker and maintain a more stable valve motion than the traditional cylindrical springs of yesteryear.

    Beehive Spring Benefits:

    Rev faster
    Lighter components
    More durable design
    Less stress on valvetrain components
    Lower spring frequency for more precise valve control.
    More valve control equals more aggressive cam profiles
    All of these items help to return more power for you to enjoy!

    If there is any indication of wear to the stock valves I would just go ahead and replace them with aftermarket. If you are already replacing valves it does not cost much at all to go with aftermarket valves. Quality aftermarket valves are both lighter and stronger allowing the engine to rev faster, less strain on the valve train, more resistant to heat, etc. Ferrea makes great valves, and the shape of the super alloy valves themselves increase air flow resulting in more power. I have also heard good things about Supertech valves. BC makes a decent inexpensive valve, but after about six months in my engine one of them was burnt so I went ahead and paid the additional cost (like $40) to go with Ferrea.

    On the other hand, if the stock valves are in perfect condition the cost/performance increase you would get from aftermarket valves isn't really that great so it's something that could be skipped.

    To realistically dive into a heads properly, carrying over buckets and not counting cams...you're looking at $xxxx or so with your supplying cores. That's bronze-manganese valve guides, Ferrea Comp Plus valves, Ferrea dual valve springs, Ferrea valve seals, and port work. All of my work is a custom job carried out by headworks. It's the good stuff.

    I really don't think you need it unless you are really trying to get that LAST BIT out of your set up. Most people also ignore the increased heat rejected to the cooling system via thinner exhaust ports...food for thought on track days.

    With you not seeming so worried about the top end of the curve and this being a fast street car/DD set up, don't sweat the heads. It's my $0.02. If you do want to get heads done, I'm happy to get it all done for you.

    I'd suggest GTX3582R or going with a good 272 setup before I said dropping the extra money on portwork.

    ^sound advice. There are more economical ways to go about making more power (ie, larger turbo). But it all does work together as a complete system.
