We don't currently have any plans to make a grind like that, no. Heads and cams need to be matched to each other for best results ... there are known, well understood relationships between head flow data and optimum cam specs as they relate to the airflow demand of the motor as defined by displacement and rpm ... and we're completely focused on matching our work to our cams. Not that we couldn't go down the path of preparing heads to work best with the W9BS specs, we could, but we're pretty happy with the path we're on, we think it's a better way to achieve our goals.

Red, I'm here in Maryland and have the W9BS cams. I'm interested in this customers build, what other motor work does he have done? Well, I don't want to hijack the thread, so I'll PM you.

V8,

i didn't build the original motor, but I was present on the dyno runs.. don't remember the exact specs..

the bike was an older buell, (Thunderstorm?) and had some trickery done to the heads..

like Aaron said. they need to match the head work to the cams..

I opted for making all the accomodations except the head milling for now. I will try the engine with the 600 cam and decide whether to switch to the 660 cam at a later date. At that point, it will just be necessary to mill the heads to accomodate the 660 cam.
So what if you wanted to go the other way.. if your heads are set up for the 660 cams but wanted to try the 600 cams? I'm guessing the duration difference would bump the compression up a bit.. Clearancing has been done for 660 so I'm guessing they should be bolt in? Base circles are the same so pushrod geometry is all good? I have the AV&V VSK6500 springs. I get the feeling I'm missing something looking at this!

If you were on the edge of detonation with the 660’s, installing the 600’s could be an issue. They are talking dynamic compression ratio (of course)

Otherwise, there shouldn’t be a problem with less lift. The only caveat is if that spring needs to be set up close to coil bind at max lift to avoid spring surge at the RPM you run.

(Disclaimer: generic engine building response, I’ve never used any Hammer cams)

Thanks maxeffort. I haven't had much experience in engine building. Its an engine that's coming together so hasn't been run yet. Bit of a extended time frame haha. I have to admit I don't look so much at ratios I go by CCP pressure. Was aiming 190-200 but calculator has it coming about a bit lower than that .. low 180s from memory. STD heads with big chambers that I still have to clean up a bit with a dremel. Can you run thicker gaskets to lower compression a bit if needed?

Could you please elaborate a bit more on the spring setup close to coil bind at max lift and spring surge...They are single coil springs.
Thanks

...actually I guess thicker gaskets would screw up my squish. .045 -.048 it's is now

Thicker gaskets are generally not a good idea. It increases quench distance and that invites detonation. It’s better to increase the chamber volume or reduce piston dome size / increase piston dish volume.

A lot of times, but not always, a spring performs best when set up .050” to .060” from coil bind at max lift. Spring surge is an out of control motion, kind of like if you had a slinky and you had one end in each hand, moving the coils from one side to the other. If the spring is set up close, it helps to dampen that motion.

It’s usually the worst at a specific RPM range because the spring has a resonant frequency. An engine that’s operated over a wide rpm range and doesn’t spend a lot of time at any RPM, may never experience spring surge, no matter how they are set up. OTOH, I’ve had expensive springs fail quickly because I didn’t match them well to the (high) RPM they were always running at, despite being set up right.

Ah ok. Thanks! What about using high lift springs on a low(er) lift cam?

Sure, .650” max lift spring and you’ll have .600” lift.
Looks good to me!
