<div class='quotetop'>QUOTE (Tyrie @ Mar 11 2008, 07:05 PM) </div>Not sure on the price of the head but a full rebuild with new valves and seals etc is roughly $500-$600.

When you get the head get it surfaced, Vacuum test the valves, change valve stem seals. Take it to a reputable engine shop and get them to check it over.

Have you thought of using the bigport head?? Ive heard and thought that they would be better for force fed 4ages cos the bigger intake ports would allow more flow when boosting. Small port would be better for NA applications.
Just a thought

i second that tyrie

minus tvis of course

[Tyrie]

yeah I'm not running tvis anyway for space reasons.
My theory is that even if smallport head doesnt increase top end power the increase in midrange from earlier boost will make it a faster car anyway.
comments?
