did you swap out the oil pump and timing chain? My plan was to go with a Texas-speed vvt stage 2 cam kit. Comes with new springs and push rods and the cam phaser limiter. Most AFM delete kits come with head gaskets, valley cover, lifters, lifter guides and head bolts. Do I need an oil pump and timing gear setup? I’ve got 95k on the clock. What head gaskets are the go to?
