71 318, has 340 heads on it with oversized valves. i cant remember any of the sizes or numbers i put this together over ten years ago and drove it ten miles and have ran it a couple times over the years just at the house. the valve train has some noise. all new lifters, push rods, i THINK the cam is a .488/.488 if i remember correctly. nothing horrendous sounding but does make some racket, almost sounds like a solid lifter car. the rockers are stock non adjustable, i had bought a set of steel adjustables, never put them on the car, i am thinking this should solve the noise, that the stock non adjustable lifters and size of the cam are fighting a bit with the lifters and thats the clacking noise? car runs real good just some noise. i know those non adjustables have to go and arent helping. anyone have this issue? have to figure out what lash to set on this also. thanks.
