people say that you can use holden red springs in the A series motor. I was running copetition springs CB4A02.(or is it performance springs? I can't remember which is was) Anyway my cam is poked with valvebounce damage, so I want good springs for my next build. I have two mates who work at holden, (one of then works in the parts dept) so I'll be able to get em at trade. Plus I've heard that the springs I was using only have a given life span. I just bought a head with monster inlet valves, and there were a few springs rolling around in the box. They seem to have a very short installed height, and there were some gigantic packing shims in there too.
Anyone have the part number for the holden springs? or do people use the competition springs springs for the holden red motor? (Even Feral reccommended them ages ago)
