i have a '97 camaro with a tuned port 3.8 engine. the heads were cracked when i bought it so i replaced with reman. ones, so far so good. when i got it back running the lifters were making their little noise and would not shout-up after driving it for 150 miles and several tricks so i relaced all of them. got it running again the lifters are quite but there is still a ticking sound coming from the front of the engine that goes faster when idled up. could this be a bad new lifter, or timing chain slaping or
????. any and all help will be meet with a million dollars or thanks, paul l. brown
