You could add head work and the CR 575 cam when funds are available.

Probably better to just save up your dough until you can get the heads done before you make your next move w/the 103 and then your heads will more than likely need manual compression releases which will have to be pressed everytime you fire up your motor.
Either that or try to get heads that are set up for ACR's.
I am in the same boat but have purchased newer heads that are set up for ACR's and have also got the harness for them, Andrews 57H cams,
S & S 107 jugs and CP pistons. I need to get the heads staged II which is more or less $900, plus stiffer clutch spring which might entail getting a AIM/VPC new tune and maybe a new tuner since what I have now is the PC-V which is a piggy back as opposed to a flash tuner.
So yeah it all adds up real fast as has been said.
I think if I could afford it I would sell what I have thus far and just get a S & S 124 for another $2.5-3 K, but even then you'rte not completely done just because you get a bigger motor.
As is said, speed costs, how fast do you want to go?
