Alright i have a 98 gsr that has been modified for a turbo kit but the
guy i bought it from did not replace the injectors like i thought he
had. so it was running lean. anyways i put some double prong titanium
spark plugs in. which i found out later was a terrible mistake
(apparently you are only supposed to put coper plugs in a boosted car.
anyways to make a long story short, the plugs i put in, literally
exploded in the combustion chamber and took out an exhaust valve and
left a ton of metal all over on the head so my question is...

Where
is a reputable place to send my head for machining, port and polish,
and all that fun stuff? I am in Idaho falls and everyone i have talked
to told me that i need to send it away cause no one here really knows
anything about hondas/acuras. Good and low cost is definitely preferred.

Also, should i replace my pistons? turns out they are stock not turbo
pistons is that ok? and there is a bit of metal on them too from the
spark plugs but i could probably clean em up if i keep them.

any help you can give me would be awesome thanks
