I had the W6 in my top end only built 80 Evo, Hillside ported heads S&S E and D&D 2:1.
street tuned than Dyno tuned, while I did like it, way more power than the EV27 but I did immediately want more. The W6 has got quick ramps, but its still a street cam. Good for 80h/90t

I plan on sending a set of heads out to hillside and also have the ev27 cam but have been debating on swapping it for the w6. The bike has 10:1 pistons, jugs bored .030, v+h long shots, cv carb, and oem pushrods. Thoughts?

Not directed at me, but at 80 inches it sounds great. Either cam will make nice power. If you’re willing to keep rpm’s up into north of 2600 most of the time, I like the EV46. If you did 10.5:1 with ported heads I’d do the EV51.

I really liked the W6, you will also, I didnt mention it in first post, I was also at 10:1 with Wiscos and of course you will need ignition system. The W6 is a little and I mean just slightly noisy. It was fun though and this was my just out with guys bike, as hooligan as a springer could be.
Surprisingly quick fooled a lot of guys when they got dusted.
You will probably be slightly limited HP/TQ in the pipe choice, 2:1 pipes are just easier to tune. But if you are happy with the look it can be done. I dont think you are trying to make a just for fun drag bike, like I was, and like I said, I wanted more immediately. But the compromise is I still wanted drop in reliability and that is the trade off with street cams vs something really radical.
I am and will always will be a Hillside guy, and strongly believe in talking to whoever you do pick for headswork, they should be involved in your cam choice, Scott @Hillsidecycle.com has done thousands of combinations and your expectations can be resolved with a quick call.
Unfortunately I dont think Scott hits up the forums like he used to.
I currently have the EV27 in my 92 FXRS and I actually like it, and I am sure there is no head work on this motor.
pic just cause I can. Class winner in Evo

I have heard that they can be noisy if pushrods aren't adjusted correctly. So a significant difference in performance between the EV27 and W6? I have wisecos also; i believe mechanic had to go with a thicker head gasket b/c clearance issues. It maybe had to do with the aftermarket jugs I used.......Also, I was wrong on my pipes, they are the bigshots (long) with the hidden crossover. Yea, I plan on talking with them about cam, etc. when I'm ready to get the work done. Nice bike btw; congrats on the win!

The Indy that assembled my motor, well took it apart first and myself thought my Evo was a complete dog stock, it ran well, mileage was fine, no leaks etc. but just didn’t seem like it made the power.
we where both surprised discovering the EV27 already being in the chest.
The noise issue, mostly we run open air cleaners with modded engines, I ran the double snorkel from S&S and any open air cleaners contributes to the noise coming out of the engine as it sucks more air in. That combined with a rowdier bump stick = (cam) valve lash is the same, they just make more racket than stock. Someone with more than day around stock Evo’s will know you got something in there.
all good fun!
Now I have another used evo with the SE kit and the EV 27 and while it’s slightly lighter bike than the springer,, it actually feels like it has really good power it’s running stock head pipes with crossover and SE AC and mufflers.
Since it’s all original with OEM mods it’s going to stay that way

Really need to know what compression is in the engine before making any cam changes, if it's something like a Big Dog S&S it's going to be a slug needing the compression bumped and the 585 will do well. Been kinda confused because the S&S V111 with a 585 puts out descent hp & tq numbers and you should be smiling when whacking the throttle.
W6 needs the lifter depth set at .150 instead of .100, helps soften the cams square lobe shock after cylinders grow from heat.

I apologize in advance, not trying to hijack the thread. Ive had the bike for 15 years and the work was done about 10 years ago so my memory is a little foggy on the details but i remember the mechanic saying he had to take it apart again b/c maybe piston hit so they had to change gasket. I tore down the engine a few years ago and checked my pics but cant tell what size gasket was used. All i know is it was mls. I dont see any numbers on the gasket. So long story short im going to have to break it down again to find out head gasket size before picking a new cam and/or getting heads sent out?
