Cylinder Head Question ?

[sindako]

Hello Mates .

See , I've Heard There are More Than One 2.5 Cylinder head For the BMW m20 .

I Saw a cylinder head with 2.5|2.7 stamp on it .
And Another One With Only 2.5 On it which Came from an E34 ?
Are They Different Than Each other , By Flow / Exhaust ?

Or Are They The same , in case of e34 never came in 2.5|2.7 ?

And Should Take the 2.5 one or Take The 2.5|2.7 ?

they are the same. the one with the 2.5/2.7 stamp on it is from a later M20 and was also used on the "2.7 Super Eta".

Thanks For the Info Mate .
I'll Also Take Both To The Cylinder Head Technician , and He'll Tell Me Which One is Better and Has Less Miles .
Thinking about Port Polishing it TBH .

My Car is On 2.5|2.7 head , but that one i am getting is for another project .
Maybe Super Charging or Boosting , Still Doing some Financial Studies To Do this .

thing to look for on the head is cracks in the cam bearings.....
