Why yes you can. For a price
It started out as a simple valve job, mill and reshim.
He has since decided he wants to do some major work on porting it.
He estimates 80-100hrs in it just for porting lol.
Now i may have to go for more hp
Ok so head is almost done. Just need's assembled and shimmed
Also if money allows it there will be some BC stage 2 cams as well(crossing fingers)
Going to order arp headstuds and Titan MHG this coming friday

Got my head back late last night
Just waiting on Titan Motorsports to get back with me on my headstuds and MHG
Hopefully have it back together and running in 2 weeks...then park for the winter lol

Update
Assembled the motor and its running again
Went with stock headgasket and stock headbolts torqued to 75ft lbs
Will update with pics in the next day or so

Metal Head Gaskets REQUIRE the block to be machined. If you replace a head gasket with an MHG and you dont machine the block you're going to have another BHG.
MHG = Machined Block. Every. Single. Time.
This is one of my pet peeves of the mk3 community. Other communities, namely the 4 cylinder crowds can get away with it more easily. With the long sealing surface of an inline 6 it's prone to problems. The makers of all the MHG's specifically say you MUST have an RA below XX which you will only get with incredibly skilled lapping work or machining the block deck.
If you can't get the block machined, DO NOT USE AN MHG.

I realize that. Somehow I thought he had done a complete rebuild.
In that case, good move sticking with the OE gasket.
Thanks rx7nut for explaining my choice.
I don't want to pull a motor for a metal head gasket if I'm going to be keeping a stock bottom end for now with no extra money for a rebuild.
If it blows again then I will replace it until I'm ready for a complete rebuild
I will say the headwork that I got done. Really helped with low end torque
Still need to update with pics
Also suppose to be getting another auto trans with low miles.
In which I will have valve body modified and shimmed accumulators

Ok so here are some update pics
My billet cps cover that i polished up:
My turn signals that i polished up:
My n/a valve cover that i polished up(will be installed once i get jz coils and possible ffim)
Now for assembly. My fan shroud was cracked and would cause harm if it broke so i kept it off til i buy new. Mounted air filter so it wouldnt hit fan blades
