Hi Tom,
Sorry, I don't have a blower manifold for a Boss.....wish I did. As far as the rockerstand situatiuon, you're right. The AR stands are kinda flimsy, I had to re-make those too. I also pinned the stands to the heads to eliminate any movement.
These Boss' are a bit finicky when it comes to the valvetrain, there really is a big need for someone out there to start making a reliable bolt-in-place replacement roller rocker for the stock Boss heads. Just try and convince someone to start doing it......
Thanks Dude!!!
Eric
