Why not go ahead and get them just to be safe? They're not that expensive and its not a hard install.

Heck technically I can run 45-50lbs of boost on stock head bolts, but Id rather spend a little money in preventative mods than break somethin more expensive down the road.

Here's my problem, Ive had my intake and exhaust 60lb springs now for about a year but havent had the $250 to get them installed, and a little scared to install them myself. Should I go ahead and attempt doing it or should I go ahead and bite the bullet and pay to get them installed? Btw this is with the head still on the truck, I dont want to remove it to change out the springs. Ive heard that you can unbolt the body bolts to get to 5 and 6 but not sure. Tell me what yall think.

Its a pain to get to the last one or two cylinders, but as long as you have a spring compressor and a good pencil magnet its not a complicated install. Ill give a link to an article Whit had on determining when each cylinder is compressed so you dont drop a valve. Followed his instructions and didnt have a problem.

Hope it helps ya out dude

Shouldnt take more than two hours max, depending on how well you can get to the last two. I did mine on a Ford, so Im not exactly sure how hard it is to get to the last two on the Dodge.

Haven't done it yet, but Geno's Garage sells a valve spring compressor that you can use a bolt with to get to 5 and 6.
