hey, does someone tried to use m43 valves in m20 head?
going to use m43 intake valves in my engine, but I have some questions
m43 valves is ~2mm taller than m20 valves in full lenght and also from big end to valve cotter grooves.
so, what should I do to keep stock valvespring setup, put ~2mm spacer behind head and lower spring pad?
M43 left, M20 right
as you can see, M43 valves looks better designed, slim, and they are ~13 grams lighter than m20 valves
outside look
