Lets check them first.
Pull the green wire off your starter solenoid, so it won't turn over.
Next put you finger in the hole in the middle of you valve covers, and hit the start button.
You should be able to feel them move.

As 1 who does a shit load of cylinder heads, something I'm finding more frequently with S&S and also Harley Davidson Twin Cam engines with automatic compression releases is the vent holes in the exhaust port to the release itself get clogged up (packed) with oily carbon. I use a .150" round rod to clear the passages on Twin Cam engines, and a thinner diameter wire on S&S heads. Remove the compression release and exhaust, and have at it.

That has been a common problem with S&S releases since day 1. IMO, that's why they stopped using them on their Twin Cam heads. Now for Twin Cams, NOT EVO style, they have easy start cams.
