my upgrade

[bushyg40]

well guys my valve stem seals were well past their use if u get wat i mean so i ordered a head set and thought if im taking the head off y not do the rest of the head eg cam porting charger  [attachment=40]
and i saw this on ebay
[attachment=44]
so i had that then thought well need more flow so i started porting the inlet manifold [attachment=39]
then i done the inlet of the head
[attachment=42]
[attachment=43]
thats so far anyway any comments welcome

rehost the pics matey the forum seems to have gayed them up.

[bushyg40]

tried it just done the same

[hayesey]

they're just miles too big.  I need to make the forum automatically resize them but it doesn't right now.

[bushyg40]

anyway any comments welcome

[hayesey]

you'd be better off making the pictures so they are just links, so people can click them and it'll open a new window showing the whole picture.  Or make them a lot smaller.

If your doing all that work on your head, then I recomment changing the valve guides as well as the stem seals, (I say this as my guides where badly worn on close inspection and the valves stems themselves had taken a harmering too(so new valves all round too).

Can't tell much from your pic's (if you can resize them would be great), but when I did all my head porting work, I used an old gasket to act as a template and therefore matching each head port with each manifold port thus creating a smooth transition between the mating parts(in my opinion thats inportant than getting greater diameter). Generally I found that the exhaust manifold(PSD) and the GT inlet manifold that I fitted were both larger bored than the G40 head, but port offsets were different so matching edge with edge is crucial.

with the gaskets you can grind away a coulple mill off them too and get a bigger bore and ye its all port matched
