Default Adjusting valves on boosted car

Should I gap my exhaust valves an extra thousandth or 2 to compensate for the higher egt's or should I just stick with what Honda engineered?

I've always stuck with the lowest clearance within spec. Always ran great that way.

.007" on both in. and ex.?

Does anyone know the stock lash? Is is .008 in. and .010 ex.?

And thanks for the previous replies. I've talked to a few other guys and have been hearing the same thing from everyone, keep it stock.

i believe stock setting is .006-.008 intake and .007-.009 exhaust, the .007 for both works. i usually do .007 in and .008 on exh just to be sure not too tight.

but also dont know what you are aiming for but if it is trying to get that extra little bit of power i wouldnt worry about it on boost like i would motor since the air is being forced in its not that critical. so i wouldnt really go to the minimum on the exhaust or anything.
