401...adjustable valvetrain?

[CJim7]

Havent even pulled the valve covers yet...Im planning on pulling the heads to replace a "stuck" lifter and someone (who also has a 401) said they're adjustable and that might be the problem.

Im used to a non-adjustable valvetrain such as you would find on your typical 4.2l. Still learning about the V8, so if anybody can give me a rundown on what's adjustable (lifters, rockerarms, whatever) i would much appreciate it before i start digging into this thing.

Thanx :-|

If they have independant rockers then they are adjustable but if they dont then their isnt any adjustment and you have bridged rocker heads. What year is your 401?
