My 360 Six Pack build!!!

I did had an issue with the 273 rockesr and I wasn't able to use them.

They were hitting the valve spring retainers badly and also the pushrod cup was hitting the rocker at full lift, I don't have close up pictures, but they were a no go, at least without some mods.
Since my friend had two other adjustable rockers sets in hand, one being a Crane stee/lductile iron and another a Proform Aluminum, both 1.5 we gave them a try. I didn`t wanted to go with the Proform, so we first tried the Crane, but it was still hitting the valve retainer. So in was the Proform and everything cleared OK.
I'm not sure about keeping this rockers in the engine, but for now they are in. Only thing is that I'll be changing the adjusters with some Crane adjusters, to improve those a little.

What do you think about them? Will the Proform with Crane adjusters hold up? I'm planing to rev this thing around 6500?

Any comments will be much appreciated on this matter or anything about my engine!!!
