Default 02 4.7 rought idles dies

I just bought a 02 ram with a 4.7 had a blown head gasket and 3 valve seats dropped valve barley touched the top of the pistons also cylinder walls looked very good not scratches or marks. Took the heads to the machine shop and got them fixed them put the new head gasket and everything back together timing set right. Now my problem is the truck wont idle shakes and truck will not start unless i hold the gas to the floor also have a tapping/knocking noise under the intake. Any ideas would be great also im only getting 1 code and it is P1491 getting pretty frustrated with the truck.
