Who do you think i got to do my head. Somone who is experenced with "stock" classes. Id ask you to get off your high horse, but well, it's not that high to start with...

Harsh Walky,
Don't really know what you mean though. Many people such as yourself seem to take a lot of info but never give any. J%* in particular do not give away any info, as I'm sure they've spent tens of thousands of dollars to get where they are.

I spent a lot of money doing things by trial and error, a few years ago, and now tell guys how to save thousands.

I don't really give a toss where you got your head done, but you held back on telling the bloke, but nearly cried when I told Him the answer to a question which he asked.

Don't want to give away info either hey buddy.

I am sending you a box of tissues Walky. :

Heheh.True ,true true :Reverend: You dont need any porting to gain
10-25 %

why do you suggest ef valves heckaz?? the first of the thin stems was the very late el hybrid engine

well i rang up the place thats doing my head and asked to get it flowed before and after and he said no prob so i guess we will find out what mine flows standed. i asked him aswell and he said between 320hp and 330hp. he is going to try a few things with my head but if i just get done what he normaly does he said she will be flowin 370hp to 380hp, but i think he wants to get more out of it (and so do i!) so that should all be done by the end of the week.

Well, I have no doubt you will be able to achieve the power figure you were chasing. Look at what vegabass and a couple of others have got. :Up_to_som

The BBM is actually a good thing, and contributes to the fact that many Fords with them have made more power than their head flows. :1syellow1

eg. many stock headed Auto AU's have made 150rwkw
stock they are about 100rwkw this is a 50% increase on 157kw
= 235.5kw @ engine, which = 315hp @ engine, with a head rated as flowing 300hp or less. :

well me head is there at the moment. i gave em a ring today and old mate said he has got the intake to flow 400hp and wanted to know what i wanted with the exhast to flow. i asked him to put the bigger valves in there so it should haul ***. anyway i'm getting it back soon so i'll have the standard flow rates and the performance flow rates aswell.
