wanting to swap a few 6.1 parts onto my 5.7

I would use the Non-MDS lifters and plugs out of the 6.1. Pushrods, too. They're supposed to be a little longer for correct preload.
That is fantastic news, got some customer work to do tommorow morning but gonna pull the heads off of the 6.1 and see if they are ok to use aswell as the other parts. Do you know anyone that might want the 6.1 short block when I'm done.parting it Just because I dont have the cash to get the machine work done and already have a good5.7
Not sure what went wrong with it yet
Should no more tommorow
