My 5.3L just hit 186,000 miles and is starting to make some valvetrain noise on start up. Going to do heads / cam / and new converter. I my thoughts are the PRC STG 2.5 5.3 heads milled, the TSP 220 or 224R cam and the PI converter 2800-3000 stall tuned by Nelsons. Truck is not a DD (have a 07 ZX10R for that) and will be getting 4.10's and a tru-trac.

Any suggestions or changes?

Thanks in advance.
