Could be exhaust leak. Use a stethoscope or screwdriver as one and pinpoint the area. Double check torque on bolts now that you have a few heat cycles done.

 

Ok

 

Hey thanks for that advice. That is definitely a possibility. I have a bud who's a small engine mechanic. We're gonna go through it together. Definitely top end after he heard the video of it. Regarding the exhaust. There's some shiny part of either side of th header still sticking out, this made me think it wasn't pushed jn all the way however when I was building it, I must have taken it off and put it back on 2 times with new exhaust gaskets. So am pretty sure its all the way in. Regardless I can even go with some soapy water and see if it bubbles there. Head bolts were re torqued, valve lash re adjusted, no leaks anywhere that I can see. Next up is that pin point test with the stethoscope. Thanks for the advice ill update soon. Any other advice is always appreciated. Cheers

 

I've posted a video on reddit. The post is called shes a ticking. Its very odd. Thanks again for any advice

 

Might be worth getting a boroscope if you haven't pulled the head off already. That way you can see inside of it and look for damage.

 

I think ill pull the head anyways. School picked up so im letting it sit for a while. Ill update with pictures and my findings when I do so.
