Question about lifters

[91lxstang]

Stang gods please help me! I'm up to my elbows in a head change, and I need to know what I should do? I've heard that sometimes the lifters can collapse, from the valve spring upgrade is this true? Also if it is, should I get new lifters? And if that is the case, is it bad to use the old cam (stock) and new lifters? Thanks for any info!

Your stock lifters should be just fine. If they are still in good working order then you will be ok. Classes like Street Warrior require the use of Factory lifters and they work just fine for them.
If you were to get new lifters then it would be ok to run them with your stock cam. Roller lifters are very forgiving when it comes to changes.
