I have a 1967 289 that I have been upgrading with new edelbrock aluminum heads, roller rockers, intake manifold etc. but have left the stock tappet cam and lifters. The engine has a loud clicking noise at the rockers when starting, and it goes away after it starts up. I have tried a few different oil additives to see if that would fix the problem, but it hasn't. I also had to go back and readjust the rockers as the valves became out of adjustment once the engine had run for a while.
Short of replacing cam and lifters, what are my best choices? Can I remove the lifters and service them if I put them back in the same spot? Replace the lifters and hope it doesn't wipe the cam? Let it be for awhile and see what happens? The engine actually sounds fine after it starts, but it really is loud clicking and it is hard to start at first crank.
Thanks for any advice, Mitch
