Anyone here remove or drill out a bigger hole for the head oil restrictor that is in the block ? My friend removed his and he doesn't have any problem with this but I think this is a bit overkill. I was more thinking about drilling a hole the size of the exit of the restrictor, just to give a little more oil flow to the head. Any input would be appreciated ? Thanks.

 

removing the oil restrictor doesnt really hurt anything, but the reason that is on there is so the head sprays into the head. you know, high volume through a small hole creates pressure. if you open that hole a lot, then the oil just kinda sugs in there, rether than spraying in there like it was designed to.
