I'm thinking about picking up a set of the 180cc ProAction Lightning heads, as I can get a decent price on them. But, I haven't seen ANY times, builds, dyno#s or anything from any magazine or anyone on these types of boards. I've heard from some that they're quality pieces, and from others that they're cheaply put together.
Does anyone here have any concrete #'s using these pieces? I'm weighing up going with these over the Vortecs, but I need something to go on here. Anythings gotta be better than the 882s I've got on there now though.

Thanks guys!

 

my dad has a set they seem pretty good, and clean castings, only thing we had a problem with is the rocker studs that came with ours had no shoulder. you just bottom them in the hole, .....well that only lasted 15 mins, before it spun 3 of em loose, get a set of ARP studs that have a shoulder, and you should be fine
