Default Cams

I have an 08 street glide tgat I am going to convert to a 103 this winter but I'm stuck between these 2 cams

S&s ez start .551
S&s ez start mr103

I want to stick with the easy starts due to the fact I don't have acr and I'm going to use the heads I have on the bike now


Any input from those who run these cams would be appreciated I ride mostly below 5 grand a lot of the time

I have the mr103s in my breakout. Runs about as good as a stage 2 can run. I'm sure others will chime in with other cams you haven't asked about but I hope this helps a little.

How do those cams perform at low end?

Also I assume that them being a bolt in cam that stock pushrods and springs will work with the .585 lift

I have 0 issues with the low end power. I have been 2 up plenty of times up into the mountains and everywhere else. The way I ride it suits me fine. I tend to keep the rpms over 2500 , meaning I d rather downshift to keep from lugging the bike anyway. My bike is a 2013 and yes the heads and springs are stock. I used s and s lifters and adjustable pushrods.
