Well I've put maybe 100 miles on my motor it wasn't an overhaul just heads. Cam etc...I drove it 40 miles to the headliner shop and when I picked it up i no iced a tick tjat o figured was an exhaust leak...well a few miles later ir got louder...so I stopped and took it back until I can haul it home...and by ideas?

Sounds like it could be valve train noise? Press-in or screw-in rocker studs? If press-in, possibly one pulling out? Weak lifter or flat lobe? From the looks of the dizzy vacuum hose movement, looks like it's missing, is it? Almost sounds like a compression leak also?? Loose plug or a broken insulator? Hard to tell via the inter-web. Let us know what you find. Hope nothing serious.

Definitely valve train. When you did the heads, were they the same ones or different ones? Did you check rocker geometry? I'd hate to think something 's lunching itself. Smart that you parked it.
