M20 885 Cylinder Head w single valve spring

[Motorsport1207]

So is the only difference between a 885 std head and 885 super eta head is the single valve spring.? Is the cam different? Does a super eta head provides more performance to the M20 Sent from my iPhone using Tapatalk

Ok, Still learning here. So my next question is what is a super ETA head and where is this used. Can this be used in a standard M20 325 engine? Thanks Sent from my iPhone using Tapatalk

the super ETA cyinder head, is exactly the same as the 325i cylinder head. add the 325i twin valve springs and camshaft, and you've got a 325i cylinder head. i would not recommend installing it on a 325e engine. you will drastically lower the compression.

the cylinder head with single valve springs, is off a 325, Super ETA. the camshaft is also different, than the one found off the 325i.

What is the difference between the 885 cylinder heads that has the dual valve springs vs this one that has the single valve spring. Thanks in advance Ted Sent from my iPhone using Tapatalk
