Surfdog’s 71 240
Building this 3.2 motor, I bought this e88 head to replace my e31.
Supposedly the e88 will flow better on the L28 stroker block. (According to the guy who’s helping me design my 3.2). They look IDENTICAL to me.
I hear the combustion chamber is better and the compression is better. I honestly can see any difference. 
Once I clean them both up, I suspect they will be identical. I e heard the valve seats are different?? Who knows.
