The strangest part of it all is that there is no issues with IPA/APA style beers. Only the higher carbed stuff.
Tried everything but still have foamy beer from keg.

This comment makes me think you are pushing the foamy beers at the higher carbonation PSI, instead of the appropriate line PSI. Are you purging the higher carbed keg head space before serving to make sure you are pushing with appropriate carbonation?

Is this homebrew or commercial beer? My connection s slow so it is a pita to get through the pages. If this is home-brew I would my first assumption would be you over carbonated your beer. If you have checked all of the other boxes listed (line length, diameter, poppets and frozen lines etc) and this is homebrew then I would consider taking the keg of gas and purging all the co2 out do this every time you get a chance over the next few days/week leaving it off gas and it will get back in range.
I have several times forgotten a keg a to high a psi while carbonating and gotten pure foam until I remove some of the carbonation. If its a commercial keg then I have no clue.

Ding Ding! we have a winner here IMO
I like carbed up beers and so I have to do this all the time.. Occasionally upping the pressure again and letting it hold for a couple days so as to maintain my tongue tingling target zone. As continual purging will flatten out my beer below where I like some of it.
The flow control perlicks are probably in my future some day which will help but probably not eliminate it.
Ah yes...foam...probably the only real bug a boo to kegging I have found.
Another trick I use is to completely purge all keg pressure at initial beer line hook up to that keg and have the regulator turned down to no flow.. Then holding a glass under the tap and the tap fully open, only then very slowly bring on the gas pressure as your drawing that first beer....it will purge and cure most all the "trapped gas issue" of CO2 coming out of suspension in the line due to the fact that the line gets filled nicely with solid fluid only ( beer)
Like Rush (and others) said, this means you have nothing wrong with your kegging system and that your kegged beer is probably the issue. What pressure are you carbonating your higher carbed stuff at? What about your IPAs?
Even if you drop the regulator pressure down before serving, you still have to purge the head space. Also, it's going to take a while to reach equilibrium again because the higher carbed beer will now outgas and you'll probably have to purge the keg again before pouring smoothly.
Are you absolutely sure you're using 3/16 vinyl? I use much shorter lengths for brews that are pressurized around 17 psi and 38°F. If you're using that long lengths, you still might be having issues with the shanks/taps warming up too much. Try pouring a foamy glass and then another right after. If the second is not foamy, you have temperature issues at the taps. You can also try wrapping the beer line around the keg so that the line itself stays cold and isn't relying exclusively on convection.
You can try to make sure there's nothing stuck in your taps by disassembling them and cleaning them out with pbw/oxy and then sanitizing again with starsan (mostly to get rid of any left over cleaner).
