Having everything for a cam swap
Good morning all
I have decided to install the Andrews 57h on my 2012 flhrc. I have also decided to get new pushrods, lifters etc.... Couple of questions -
1) should I buy everything from Andrews? Or does it matter (other than the cam)?
2) should I get the alloy pushrods or are the aluminum good enough?
I plan to put in the rockouts when I do this so I will need the gasket kit for that as well
Thanks

Don't put aluminum pushrods in. Unless you're a pro drag racer and take your engine apart after every run the weight difference will not be worth the extra maintenance.
Aluminum is great for high rpm due to the weight savings but it's softer and will bend easier. In a street machine it is a waste.
Now as far as buying a full kit from the same manufacture. You will get mixed replies. Personally if I were going to do another can swap I'd go with the s&s 583 for my riding style.
I do not like single ground cams like the woods. What I mean is the cams where intake timing and exhaust timing are the same. Just seems to me as old technology. The s&s cams have different duration for the intake vs exhaust and to me seems to indicate they did more research. I could be wrong but that is my 2 cents and opinion. You will find many people have different opinions

2)No aluminum. SE (adjustable) pushrods (PN 18404-08) can be purchased from a local dealer or an online discount dealer at a 20% discount, plus shipping. Comp Cams VThunder 850.1 lifters are an economical choice, about $60 to your door, or S&S Standards which will cost a bit more.
None of my business but the Andrews 48 would be a better choice for a Stage I 103" motor. Wait until you install the cams; if you aren't currently hearing the annoying tick that the RockerLockers is designed to eliminate; you may not hear the tick after installing the cams. if this is the first time to remove the rocker covers, you can reuse the gasket.
You did not mention changing the inner cam bearings which you should do.

Thanks everyone for your responses and shopping hints :-) I will definitely buy from other than Andrews. Thanks for the various part numbers and additional items. I had planned on buying bearings - forgot about that in my original post.
My motor has 35,000 miles on it so I may replace the gasket regardless of condition just to be sure.
To djl's point about the 48 - I thought it would be the one I would get also, but my neighbor (has an identical bike to mine) emailed Andrews for clarification and got the following back - he mentions "elevation" and I live in Arizona (Phoenix).

"Typically I do not recommend the 48 cam for 103s because its over-applying a principal of short duration cams to achieve lower RPM power but larger displacement engines with higher compression ratios dont play nice with short duration cams. Being that youre at elevation you could use the 48 cam and should have no issues with high cylinder pressures."

I have the 57s in my 2014 wide glide. Comparing stock to the 57s you will see a decrease in ccp. To help counter this I installed a .027 mls head gasket. 48s wouldn't have been a bad choice considering I'm at 3000ft. My ccp is a measured 185.

Running the 48 with the OEM head gasket (.045") will not cause compression issues at the lower elevation in Phoenix; no worries.

I was in your position almost a year ago and received great advice from many including some who have reached out to you. I've included my thread on the install which had part numbers, prices, etc. to do the job. I had an absolute blast doing the work and hope you will too.
