jeepsr4ever wrotePersonally I wouldnt buy a bottle of water from Maddog/Falcon global/Fast engine parts. They dont seem to care about quality or the hobby they are just out to make a quick buck and bail. Many mfgs have pulled the pin on them.
Did you mean their customer service quality? The kit just looks like name brand parts put together in one kit. So surely the parts are fine? Also with the kit, it states that machine work is required for the "Dual matching valve springs". What machine work do you think is required? I've read that with bigger cams that the valve guides need to be shortened so the spring retainer does not hit them. Is that what they mean or does the head itself need machining? Thanks for the help so far.
