I've never heard of this outfit,but thats not sayin they aren't a legit company either.
I got a question,if you was going to use RFD why are you not using RFD (Curtis) now? I am sure Curtis has alot of experiance with these heads you got.
Also why not support the people that support us here at RJ? Curtis is here in the forum ,in the engine section,and we all know he is for real,why go else where?
I am sure he has done work here for quite a few folks,and have never heard a bad word about Curtis,(RFD)
