Yes, and Better. IMO. You can check out this thread - REDSHIFT 575 CAMS & OTHER PRETTY PARTS for a lot of discussion on the installation of the 575's in the 103 motor.

I like dOOd are happy with mine.  Pulls good from 1800-3500 rpm's as advertised.  If you do a search on 575's, you will find that people that put them in stock motors like myself and dOOd are very happy.  I believe when people put these in 103's and had head work and changed compression, they had problems.  Most about all of us went with gear drive cams and feuling oil pumps.  Hope this helps.

Count me in the "EXTREMELY HAPPY" category.  Much better low-end than before and that was with going to Rinehart true duals (which are not known for making good low-end torque) at the same time.  Do 'em.  You won't be disappointed.

Some of us were so pleased with the 575s that we wish we'd never done anymore...  :oops:

Put me in the very pleased catagory as well. Did the changes that Boatman describes and all's real good.

My wrench talked to me about the head work, I am very happy where I am and don't want to go down that down time road.  :nixweiss:
