Watch this video first to hear perfectly what this knock noise is https : //youtu.be/DEW-CCrPrgQ?t=3. I hope this isn't a rod/main bearing or i'm gonna be so sad. The reason I don't think it's bottom end releated is because when underneath the car its very clear the oil pan is DEAD SILENT, noise is coming from the Very top of the valve cover.

Heads new/rebuilt by some shitty company in flordia. Engine builder looks over heads and says they look fine, so we swap some cams,springs+retainers in. Shitty company who builds heads probably uses shitty Lash adjusters,valve guides, and roller followers. Noise is only like 1000rpm and lower, goes in and out, doesn't matter if warm or cold. also. you never hear it within the first few seconds of starting the car. Engine rpms are too high, gotta wait for them to drop and that "knocking/rattling" starts.
Let me just copy and paste my engine build that i have pre written. HI, This is my 2001 SVT Cobra I have been working on for about 6 months. Engine about 0.030 Bored over, Crankshaft shaved .030/.030 K1. Technologies H-Beam Rods,,Kings XP Bearings, Ford Racing Timing Kit+ a few timing things upgraded to Billet. D.S.S Racing Pistons, Heads were rebuilt by Clearwater Cylinder Head and I had my engine builder put in Howards Cams,+Springs,+Retainers, 255 LPH Fuel Pump, Ford Racing 47# EV14 injectors*They are compatible plug and play with ev6*, SCTX4 Hand Tuner, Dan at ProDyno got me a good first start tune for all my mods. Exhaust is BBK Long Tube Headers+BBK O/R H-Pipe + Stock Catback/Muffler., CAI. BBK Twin 62mm Throttle Body, 1 Inch Intake Spacer, Exedy Mach 350 Stage 1 Clutch, BBK Adjustable Clutch Cable, Quadrant & Firewall Adjuster, Exedy Lightweight Racing Flywheel, MMR Ford Billet Rear Main Seal Housing cover, ON3P Coolant Cross Over Delete, MMR Light Weight Power Steering Pulley, MMR Head Cooling Mod, SR Lokar Flexible Dipstick---*If You Have Long Tubes, You Will Love This*, Ford OEM Coil Packs,NGK Iridium IX Spark Plugs

Now PLEASE take a look at my next video, https : //www .youtube. com/watch?v=xu2fz9rnXU8&t . My Engine Builder said he can't tell me what it is over a video, too bad he lives 1 and a hour hours a way. But he said for me to drive it and see if it quiets down,which I have at least 3 hours of run time of this engine, everything should be somewhat broken in right? Car consumes 0 oil.
