im thinking of building my head since i have to replace the valve seals might as well replace the springs since the head ticks alil. ive been thinkin of getting blox dual valve springs. and will steel alloy retainers be fine since they are way cheaper. and in the future ill be getting ctr cams or skunk 2 pro 2 cams. im gonna boost in the way way future but now im just gonna build the head now for some fun and get a tune.

 

If you are going to replace the springs, i would replace the valves also

 

the best valve springs are eibach and ferrea

 

this list and question could go on forever.

omniman, supertech, skunk2. or since your not doing anything radical, OEM.
