so i searched the forums and i only found that people have ported the inside of the manifold and not the ports leading to the head. Would there be any gain from opening this without porting the intake side of the head? Does anyone know if the stock intake runners line up with the head size wise? thanks

 

the ported intake mani will help a bit with cooling... but other cooling mods are cheaper and easier to do first.
the runners going to the head line up pretty well factory, if you were planning on doing any porting it would be the exhuats side of the head
