Hi all
I was about to bolt my e34 head to my e28 bottom end and relised the pistons were differant on both blocks...
Im asuming because of valve clearance i cant bolt this head on without changing the pistons..
Cheers all

I'm pretty sure the B35 head just bolts on. I'm sure it lowers the compression ratio, but the bigger valves, better cam
and exhaust more than make up for it.

I'd go for the B35 management and use everything attached to the later head.

I think you need to change the front timing cover too.
