I am getting a 686 built in the near future, but I am at a crossroads about th port, polish, and valve job options. One shop has quoted me $160 for a port and polish and an extra $200 for a valve job along with larger valves. Is the valve job necessary or is the port and polish work more important? I'm not a hard core racer and am leaning toward the "mild" 686 setup. What do you guys recommend with a stage 2 hotcam and a 11:1 piston? Should I go with the $200 valve job or just stick to the port and polish? What are the major benefits of both? What all is done on a valve job anyway?

 

if that 200 includes the larger valves I would say do it........

 

A valve job is part of doing Port & Flow work. A good valve job is more important than the port work it's self. If your valves don't seal good your not going to make any power. Every Raptor/Grizzly I have ever seen with more than 10hr's on them needs new intake valves.

 

you should have seen mine,they were hammered beyond belief,must be those long drag hills..[img]i/expressions/face-icon-small-happy.gif[/img]

 

No it's the weak valve springs.

 

Anyone can polish and port a cylinder head. Where it is important is the bowl work and the valve job. Craycraft Racing does a very good job in both those areas.[img]i/expressions/face-icon-small-smile.gif[/img]

 

this forum sucks anymore. I think you guys have craycraft on the brain.

If I have offened you I am sorry but no one is forcing you to read,or to reply to the forums.
