Hey fellas,
just had local Shop build My short block I changed the compression and did MMR port on my Heads, now where I don't understand where is this noise coming from? We replaced all the timing chains even did a upgrade with the secondary timing tensioner. We started it and made a sounded like valve noise, anyone has had an issue like this? I don't think it's the short block but here's a video and let me knew what you guys recommend to start doing.

Mods
9.1 compress
MMR port on my Heads
98 cobra intake cams

Nothing else was changed and it didn't do that noise at all since
