SS Springs on 75 Duster

Good news ...bad news......Got intake manifold off....cam and lifter look just fine.....took rockers and pushrods off....removed each lifter from their bore and they all look good....

Bad news.....I dont know what is wrong now...lol

Going to change out distributor and look at the fuel pump...

Yesterday went I drove it into the garage it was still making a clicking noise in the valve train....even removed the driver side header looking for a bad gasket but it looks new.
