End of the day Iíll have a bump in compression and start easier which is what I wanted.

Does anyone know a good shop in Nor Cal that I can take the head to? Just to install MCRís.

If you want acr’s I would suggest buying used 103 heads that already have them. Thats what I did on an 06 Ultra but I also have a Thundermax ECM on the bike so turning on the acr function and tuning was simple. Otherwise just have manuals machined into your heads like Fuel Moto suggested.

As Old Hippie and others have said, getting a set of 103 heads with ACRs is your cheapest route, then do your head work. The thing to remember about manual CRs is that a hot re-start at a traffic light when stalled is going to be slower, either you take the time to push them in or the motor slow cranks as it did before. It's also possible for a manual CR to become carboned up and stick open. Auto CRs are there for every start, are controlled by the ECM, provided they don't malfunction. I chose to use S&S EZ Start gear drive cams as an alternative to both. Always there, not electronic and nothing for me to do. When adjusting push rods on EZ Starts you need to make sure the exhaust PR is off the EZ Start lobe, real easy to do.

I just gotta call you out on the post.

manual ACRís and automatic ACRís

what you are saying is manual (automatic compression releases) and automatic (automatic compression releases)

In other words ACR = Automatic Compression Release

With that said going ACR = Purchase Take Off 103 Heads which Iím having trouble finding for less than $300 and then buy the harness. Probably be into it for $400 or more with shipping.

Do MCRís for like $150-175 parts and labor.

Not sure where Iím saving on 103 heads??

Thanks for the correcting my syntax on ACR and MCR. I edited my post so it doesn't confuse anyone. Good luck.
