1 is a backcut ITR valve an one is a regular GSR/B16 valve from what i can tell from the blurry pics. hell , with that quality it might be a Chevy 454 for all i know. Valve angles are SLIGHTY different in an ITR head, which is what i said in the other thread. ITRs have a lighter INTAKE valve that is backcut, exhaust valves are the same as GSR. And, like i said BEFORE, the valve throat is .10 bigger in an ITR head vs a GSR an b16 head
still, what does this have to do with the OILING of the bottom end. your stating shit i already know. The VALVE SEATS HAVE NOTHING TO DO WITH THE OILING OF A BOTTOM END, THEY HAVE NOTHING TO DO WITH SPINNING A ROD BEARING. you said
you stated taht a ITR head has different oiling properties, an its in the head, then you said a valve guide has something to do with it, but if you explained it i wouldnt understand. TRY ME. sorry man, if your gonna come on here an say that kinda stuff, you BETTER BACK IT UP. im not calling bullshit, there may be something i dont know, but at least post up some info about it, its not a fucking secret.Originally Posted by 1civic
Maybe im misunderstanding you, are you trying to say that ITR valve guides an backcut vavles provide better oiling to the bottome end? when did we start talking about head flow characteristics, we were talking about lost oil pressure an spun bearings, what does a head have to do with this? the only thing in the head to cause a disturbance in bottom end oil pressure is the OIL RESTRICTOR in the block.
