There is no harm in porting the rough areas. Low speed torque will not be impacted. However there is harm to be done with relieving. Do not do it. As for a cam, the EAB is a great choice. Almost anything else will reduce power in the RPM range your truck is likely to see.

In the old days I was not in favor of using the Forgedtrue pistons on the street. However, I have adjusted my thinking with Ross pistons. I think they can be set at the minimum clearance and work fine on the street. Do not pay extra for special ring groove machining as you will never see any benefit in your use.

Set the combustion chamber clearances as reasonably close as possible and have fun.
