Try Trail Tough, Brent has headers for both the 8 and 16 valve engines from Doug Thorley.
I never have dealt with Calmini but they sponsor this site so we won't bash them here o.k.? But anyone that is upset with them should call them and tell them exactly how they feel and give them a chance to remedy. Talk to the owner. If you get unsatisfactory results, don't use them. Your dollar is your vote. I'm sure enough has been said here to give anyone reading this second thoughts about using certain vendors. If a vendor has pissed you off, they have pissed others off and are only hurting their own business.

Adam,
Nice words, but over a decade late. I tried all the things you mentioned, CS was a joke and the owner was so full of himself that I finally just gave up.
By the way, the part I didn't post was about rocky road. Almost the same tooth pulling experience.
Anyone here remember Mario Raco? I hope I got his name correct, CRS has it's toll.

I had a few things ordered from him when he had his problems. It may have been a bit of a struggle but I received everything I had ordered from him and I was also in contact with him to the day I received my last part.
Not something I can say about the other party. But I will try too keep the bashing part out of my posts. It's going to be hard.
