I will probably be installing the JWT cams here in the near future. I know springs and valves are not mandatory but I think i should probably do it at the same time. I think some people are running the fererra valves and springs. just wanted to see if there are any other recommendations.

 

i'd also look into porting/polishing if you can while the heads are off

 

If you're going to all the trouble of removing the heads, then I would suggest a full port and polish too. If not, just change the springs and maybe get some titanium retainers to boot. Those can all be done with the heads on the car.
