96 to 103" conversion info please
I have procured a set of jugs, pistons and cams from a 2013 Road Glide with 550 miles on it. I am going to use them in my 07 Street Glide. While I am not a Harley Mechanic, I have a high degree of mechanical ability and the tools to do the job. Any advice insight and ideas would be greatly appreciated. Also, what will I need for gaskets and other incidentals? Thanks so much!

I'm far from an expert on these matters; but, from all the reading I have done, spend a few dollars and get a different set of cams. I'm sure others will have recommendations on which will work with what you have in mind. Might as well do it right the first time. Don't forget to get manual compression releases installed, your motor will thank you for it.

'13 103 cams are the same as your 96 ones. Total waste using them. If ya are just bolting on 103 jugs and pistons get some Andrews 57 cams and .030 head gaskets plus a proper tuner & tune for a proper boost. Lots more choices if ya plan headwork.

I would have thought a bigger motor would have different cams, thanks for setting me straight. I'm guessing the .030 head gaskets are thinner than stock, increasing the compression, will that make it harder to start? And if I change the cams as you suggested, do I need a tuner? Not planning head work at this point.

For about $350 you could have your OEM cylinders bored to 3.875" and fitted to a set of new pistons. As it is now, as Kirby suggests, you really should have the cylinder bores and piston fitment checked with the cylinders torqued up in torque plates before slapping them on your motor. Of course you could have the cylinders you bought bored to 3.938" and fitted to a set of new pistons for 107" of motor, which you could have also done to your OEM cylinders and saved some $$. But now that you have a spare set of cylinders, you can save some down time working with those.
A mild bolt in cam like the SE204 would work well in a 103" configuration but there are also aftermarket options as well. And yes, you will need a fuel management system with the addition of cams; many choices there as well. If cams are installed, you should also upgrade the inner cam bearings.
The .030" head gasket will increase compression about 0.25 points but will not affect starting, etc.
