i have bc4 cams and im wonderings which supertech springs to go with the regulars go up to 12.5 max lift and the hd go up to 14mm max lift...bc4 cams have a max lift of 12.3mm..both work but .2mm is not much room for error..but the pressure on the hd might be too much...

also since i asked and didnt get a straight answer will king standard bearings work if my mains are 3 brown 1 yellow and 1 black? and my 4 rods bearings are brown...??

 

Use the Supertech springs with the lightest spring pressure.

 

ok coming from u ill take that advise...i though maybe the .2mm difference might not be enough..any advice on my bearings dilema? im most likely going with oem for the mains and king for rods since acl is broke...or watever..but the king bearngs i order came with the mains already...so i was wondering..

 

I honestly don't know. I'd probably have to be there to see it and figure it out however someone else might be able to help direct you.
