A local shop here, Matts Machine, port and polished a 1g head for me.
What do you think. It also is geting 1mm over stainless valves. I should of got them nitride, messed up on that. But all in all it is a beautiful piece.

 

what did that run you ..

 

for the money spent it doesn't seem like its worth it performance wise for the fact of what happen at the shoot out a few years ago

 

It's nice and shiney. That's all I can really say about it.

 

What are the flow numbers?
I hope it works out for you. I have seen way to many people loose hp with ported dsm heads.

 

I'll see if he can do that.

 

What kind of head experience does your guy have with heads and 4g63 heads? Any reason for not cutting down the valve guides?

 

He doesn't have a flow bench.

 

He's done a few, exactly how many don't know. He has 17yrs experience. I'll ask him about the guides.

 

I told him that this was gonna be on a daily driver, with that in mind, keeping the guides fully intact adds alot more durability to the valve, assentially will last longer. He said he's done over a hundred DSM heads.
