Head gasket

[Hulmie]

ive rebuilt a few engines over the years and can tell you know that if you take your car or cylinder head complete with cams etc. they will be able to send it to an engineer and what they will do is strip it down and then skim the head and then reseat all valves, clean the lifters, put in new valve seals and refit cam etc. this should come to no more than £500. Your cylinder head will come back looking brand new. then with the head kit you will have left over the headgasket and head bolts to fit.

this will do fine, no need to get a new head as that would still want skimming if its second hand.

Is there actually much proven difference between the large port/small ports?

Ive not seen any... Its not like we see AGU's bhp topping AUM's with same turbo is it?

Jrd,

Very good question?

I guess he'd get less mpg due to loosing the vvt(would he need AGU cams) and he may need to tweek the map to suit?

We was actually talking about this yesterday, isn't there a way to put the AUM Cams and Sensors for the VVT into the AGU head or something like that?

Thats good info, Cheers for that mate. And i was only going to get a new head because i've got AUM and AGU Ports are bigger. But it seems like its more hassle than its worth...

Jrd,

from what i've seen from R-Tech Rollers the AGU's with K03s do gain a bit more BHP. BaV Is pretty close to them though...

£500 is extremely steep i pay around £200 with a reciept for this at a local machine shop in Warrignton, head comes back like new!

This was on a Calibra cylinder head though. think theres more work involved.

The only reason AGU's top most AUMs with same turbo is because they are apparently easier to map as they have less sensors and stuff holding them back.

And you can still run an AGU with vvt you just need to swap the tensioner / sensor thingbob from the AUM head which is what im doing.

When AD let me know whats happening do you think i should just stick with my head if it isnt Cracked?

Well if you can get a AGU head and inlet for cheap enough then i would probably go with that and use the bits from your head to get the vvt to work.  And as for the injectors im sure A D would be able to get them to fit

You can use your injectors in the agu head you just need spacers.

i looked into this when i was going to put some TT ones into mine.
