what's up guys,, general question here.. I have a full eaton terminator swap in my 04 mach. vmp tuned.. lotsa goodies,,, very nice.. here recently I've started hearing what sounds like a tick... drivers head.. on my way home today i played with it a bit. noise definetly gets louder under load. the louder the exhaust ( bbk into magnaflow) the louded the noise. and when i got home,, in a quiet garage, i revved it and all i could hear was the tailpipes,, no tick.. a month ago, on dyno, did a 6500 pull and really didn't hear anything then. I know ford had an issue with these 4v heads, any thoughts??
