Looking to do valve stem seals ,roller rockers 1.5 also wanted to see while im there replace the valve springs ,what do you guys recommend? Engine is stock 120k ,alky TT chip ,3 inch DP. Thanks
The stock cam has so little lift and mild ramp rates that a mild spring would be all that is needed. I would probably just leave it. I have yet to see anyone post conclusively that they have weak valve springs on a stock cam.
