Is it worth buying a JG Pro Series head at $1200? I assume it includes a 0.5mm over size stainless steel valves and valvetrain. Are they good?

 

they USED to be good. I LOVED my JG Pro series head.

It was one of the best pieces they did to my motor. But a lot of the good guys are gone, and JG has gone to hell from everything I can see.

Honestly, I'd go with Portflow. Their heads have been proven winners TIME after TIME and I don't believe I've ever heard a bad word about them.

 

JG blows now... like he said.. back in the day JG was the ****.. now not many people can get good work out of them.. mainly its their blocks but i would just go with port flow.. save yourself the headache of dealing with them.. just my 2 cents though..

 

can you buy a complete head that been worked through port flow?
