Well I just had one of the worst customer service experiences I can recall ever having while on the phone with SI Valves attempting to place an order. I'm surprised because last time they were fine. First I asked if they would do a custom order for bronze valve guides and was told "we don't do that" I started to say "well can I order.." Only getting to "well ca" before he blurts over me "ok, thanks" and hung up. RUDE. I was going to order a set for another vehicle listed in their catalog. But hey, at least I can say I won't ever use them again due to the sour taste I now have in my mouth.
