hey guys, i scored a 3in' shorty, so today a baught a new filter for it, put it on and so fourth. anyways when i was done i started the car i noticed noise coming from my head not like valve lash noise either, it doesnt sound unusal at idle but when reved it gets louder. i know bseries heads make noise but we all have said that i had the quietest head around. i know its a little silly but when i got the car it was damn near silent any ways i dont beat on this car and im stumped. wtf is it?

 

and the "noise" sounds like what exactly?

 

honestley....almost like pebbles. here is the thing, no smoke at all. nice gold oil. maybe im just being paranoid and i have to deal with fact that my head is making noise that it didnt before......im befuddled.
