They're going to bleed off after shut down....... So a little clatter after start up may be a fairly common occurance for you.
Took the car to the strip last night & ran some passes went 12.50's @ 109. I noticed in between passes letting it cool down cuz it was HOT 95 out, upon start up lifters clattered then calmed down after 15 seconds. Wondering if i should look into some different roller lifters as preventative maintenance Hmm
