Go through spring tension V cam specs keeping attention to coil bind etc . Bigger engine using going to improve valve train issues. Are bearing clearances ok ? A run bearing can close piston to valve clearances .
A slightly bent or bouncing valve WILL cause a miss big time..
Come on guys think about domestic motors !!!
Push-rods just do it at much lower rpm...Before rev limiters, EFI..
Boost + sq inch of valve is against spring pressure..As said..
That catch can will pressurise your crankcase ! It should be vented to air cleaner or section that never sees boost . The PVC is ok but make sure it holds boost .. Generally the lower your boost the more the waste gate needs to flow.. The catch can can be vented to atmo BUT won't pass emissions...

we have built.
