602962 valve springs
Ill be tearing off the head this week so i'll measure and test them, but i though id see if anyone had any experience with "performance springs" here first.

Thinking out loud here...
So the M103 has the same lower seat size as the 602. The first year M103's in 300E's had a 6800 rpm limit in the EZL if i recall. Also 86/87 had valve spring issues with them breaking so there is an updated number as well. So i guess ill get the 602 springs out and get the pressure on them and compare it to the M103. Hopefully they are the same height too.
