Bumping this one back from the horribly dead, lol

I am shopping for heads and have narrowed in on the Trick Flows. I have a set of old Harland Sharp rockers on the 906 heads currently on my motor (they have stamped hold downs + 6 point adjusters, assume they are the originals not designed for the E-heads) and figured I could reuse them, but from everything mentioned here they are too long so the roller isn't centered over the valve stem.

What's the biggest drawback of using them as is? Rapid valve guide wear if I drive it on the street? I average about 1000 miles a year.

Alternatively, are there any issues with a B3 relocation kit? I've heard a couple people mention the bolt holes in the rocker arm stands are shallow on the Trick Flows and studs are recommended, but I don't see a way to use studs with the B3 kits.

Thanks,
Nick
