Ok...been searching away for a good part of the night, and can't find a decent or definitive answer to these questions. ARGH! Frustrating!

Anyway...got a FR head coming my way that I got a good deal on, and am looking for the following info and opinions.

1) How much can the FR head be milled before interference becomes an issue? What would be a recommended amount to have the head milled and keep things safe if a belt fails? (I guess these questions are similar)

2) What cams would you recommend for a good balance of streetablity and maximum power in a 0-6800ish RPM range. Not looking to extend the rev range at this present time.

3) If there are any threads on this that you know of, please post links!

Huh? Thought it was not milled at all...are there inconsistencies or something?

 

[UltegraSTI]

its not milled...and accordin to others, it nor the stocker (moreso the FR b/c of the bigger valves) can be shaved w/o goin into interference.

So it goes to interference, even if your running stock cams?

 

[UltegraSTI]

doesnt matter which cams you have, its however far the valve CAN move. if the belt breaks is the maximum travel during a normal cycle. if a spring fails, then your really f'd...but anyways, from reports/experiences of others...you cant safely mill the head w/o gettin into interference, unless you have reliefs cut into some aftermarket pistons or run 'dished' pistons...the latter will just lower the CR back down anyway.
