I already sent this to you but I figured others might want to know what should be done in this type of situation.I would reccomend disassembling the head,cleaning it,cutting the valve seats,setting the valve stem heights if neccessary(will be neccessary to put new valves in) and installing new guides and seals and surfacing it.

I word of advice thatg no one seems to do when going with oversize valve is that you really should install new seats on these heads. the stock valve seats are maxed out with the stock valve diameters. in fact, going larger on the valves with these heads may not even be a good idea. there is a fair amount of shrouding already with the current valves. going larger will onl make it worse.
Nissan chose to go with smaller valves in the HR motors...if that tells you anything.

I like your hours policy:
that is the sort of no ******** shop attitude I like to see! I can see your customers are cool with waiting around for you:

and your Z's front splitter just screams 'no ********' because, you know, you are running so many support rods to it... I count like.. 6? are there hidden ones I can't see? that would be even more no ******** and REVENGECY:

rock on man! I am digging it... digging it revenge style.
and your INTAKE MANIFOLD! you guys are so ahead of the curve you are running a KINETIX... no one is even running them on the Z right now!

that is SICK and ******** FREE! so cool... and shiney... and tubular and revenge-cy. I can tell you know what is up in the Z/G world because you are running that NO ******** plenum.
Basically, open when we're here, closed when we're not.

Unlike any ever seen before in the high performance automotive industry.

look at the outer portion of the valves.....the are right on top of the chamber walls.......also, the short turn radii in the heads are very shallow which doesn't allow for taking full advantage of the available valve opening either.

because, come on quadcam, to them (quote adopted from their website):
