Agree. No easier engine to learn on. It's not that hard and if you take shots on your phone you'll have a colour workshop manual to reference from. 
 
If it has wiped a lobe (which is pretty common) you can bet the oil pump will be junk. The oil pump cops any metal dropped through the engine first. Yeah the filter will catch it after the pump has done its job, but you can bet the inside of the pump will look like a concrete mixer. 
 
Full gaskets sets are silly cheap. Borrow or buy an engine crane and have a crack. There are some good people on here who will help you through if you get stuck. 

Take photos, lots of photos. Get a cardboard box, flatten it out and every bolt you take out push it into the cardboard, draw a circle around it and any others you take from the same place then write where they come from. No memory required!!

Be interesting to see what it runs then. Good stuff

Yes good job indeed.  To be that far ahead out of the box and with gearbox issues is truly impressive, especially in an xe. Well done to all involved.

Oh and it's a 4 barrel car!!!!

It's not Steve's car.  It's a mate of his.  Looks like the bar has been reset.

Nah thankyou. Entertaining as always. In reality the flow figures mean squat as you'll be blowing an atmosphere or better in there anyway.  Can't wait to see the track numbers. Should be good. Hope you have the cage designed. 

Nice. We will fill in the blanks ourselves. 

The flow bench just tests at a constant pressure. 28" is the industry standard. It can't  account for boost as it relies on suction to get the cfm reading. 
Porting for boost will always draw different opinions, as with most aspects of engine building.  It is generally accepted that if you can make the port flow more, then it will make boost quicker and therefor make more power at the same boost pressure of an unported engine. 
Ive spoken with Ray Hall at length about boost and porting for boost and he simply said - do what you are doing for aspo.  Ray has been playing with boost for a damn long time. If your interested hit up his face book page and look at the Audi he is building g himself now. He is a champion bloke. Doesn't suffer fools.

So are you going to post figures of this one? 

So 240-250 peak flow?  All sounds good and the boost will make those low lift gains come on really strong. Good stuff. 

Very good information in here. Yes I do get passionate about a few things and spring pressures is one of them cause it's an area a lot of people get wrong.  At best it causes a waste of mechanical effort, and at worst it breaks stuff that should never break. But in recent times I've learnt to just sit back and watch.
 
One has to wonder why this efi engine has 'double springs' in the first place as the stock ecu is not capable of supporting big lift cams.  I'd be more concerned with that. Just to say it has double springs isn't enough. Seat and nose pressure are more important as is who manufactured the springs. 
 
I really see no reason to go to roller rockers in this application, especially after watching several factory pressed steel rocker cars run at 6banga Nats. Sure they were turbo cars that were making decent snot through boost so they didn't need massive lift and overlap Cams, but they were getting pinned run after run.
