sup guys I have a 351w with summit stock lifters that have about 2000 miles on em I pulled my rockers off recently and i think my lifters are stuck cause im getting a back fire at idle now anybody have some tips or tricks for me i only removed one side i believe one or two maybe stuck and when i did my adjustment they might have my valve open but idk just curious if i need to go with a better lifter due to my cam the specs are lift 600 duration @.050 241/249 i did have a lifter stick on me in the past but Revd the motor and it freed up haven't had the problem since

I am assuming they are Hydraulic. If so did you adjust them correctly and have the proper Pre-load. How did you adjust them???

First off Summit does not make lifters and comp cam ones are truly garbage. This is from many years of experience. By the way what type of lifters are they??? Also in the 50 years in this business i have only had a hand full of bad lifters that were truly bad. most times they collapse or fail to pump up. but we use quality parts and this is not an issue in our shop. but anything can happen. Once again how are you adjusting them????? And what is the exact Pre-load. Or valve lash clearance. If you do not know the Pre-Load or lash adjustment ballgame over. I always log the Pre-Load or valve clearance on every engine our shop builds. It is part of blueprinting. Have a good night guys.

I think there is another thread bout this. And don't listen to the guy above. He gives bad advice once in a while.
