I'm scared to ask what you paid for your dual timing chain kit through them 
a 20R chain kit from engnbldr would have been fine, heck even one from autozone would be adequate.
the cam is a little mild but should do a nice job. how long are those primary tubes on that pacesetter???
My mistake. Only the dual cam sprocket from LC eng....the chain from Mizumi, a wholesale house.
The headers tubes are 1.5 dia. x 32 L, 2" collector.
