More on the SE255 please
By bolt in, that means I don't need anything else? Just buy the cams and a gasket kit and go for it?
I imagine it would be wise to upgrade the tensioners too?
Anything else?
Bolt in means they are direct replacements and you do not need stiffer springs or different pistons due to lift.
You have the hydraulic tensioners, but if you are in there, you should replace the shoes if that is possible, or the tensioners if that is the way it is done.
Replace the inner roller bearings with the Torringtons. Adjustable pushrods, and new "B" lifters. Bout it.
