Great thanks for the info guys..Just wanted to make sure there was no random cavity near by or something..

That picture may be a little better..

Anyone???

Wanted to make sure these can be removed. They don't seem to be any sort of passage's and my best guess is they are some sort of reinforcements for the exhaust studs? Or maybe something to do with the way the head flows in stock form? Has anyone removed these without a problem? I'm not looking to do anything major to these ports, Just a little clean up and I would like to see these humps gone if it can be done. Thanks, Nick

Thanks guys, But you gave me two VERY different answers. I have also been told that it is the same as the SR engines but can one of you confirm this? Im having a motor put together for a customer who will be running the Tomei stroker kit (87mmX9.0 comp) and the tomei poncams but my engine builder needs to know exactly how far the advancement will be so he can continue to check the valve clearances to make sure the cams will not interfear the with new bottom end. Something like a page from FSM would be great if you could find one for it? thanks again

Does anyone know the EXACT amount of degree's the intake cam is advanced when activated? Or even better yet! Does anyone have a RB FSM cam chart that shows cam locations etc when engaged and disengaged like the one available in the S14/S15 SR20DET FSM(below)??? I need to give this information to my machine shop so it would be best if I could give him the actual chart.. Thank you in advance!!! Nick
