Buying heads bare
 

:D I am gonna order my heads tommrow , if i get them bare how much should springs and valves ,locks cost i will need 2;02 intake and 1;60 exhaust valves. My cam has 570 lift with a 1;6 rocker arm . So how strong a spring do i need ?

What heads...?
From where...?

Personally, I wouldnt do bare. THEY can get the parts cheaper (volume), so have THEM put them on. Pay extra yeah, but then they come complete.
I got my TFS TW's with O-ring and .600" lift springs and titanium retainers...
