VK56 heads


Recommended Posts

Hey guys,


I'm obviously new here, but I have a few questions for those more knowledgeable than I (doesn't take much).


1) Anyone know the bore spacing on a VK56 block?


2) Anyone have flow numbers for VK56 heads?


3) Is there any aftermarket for the heads? (mainly cams and springs)


Thanks in advance for all your help guys.

Did you mean "kjones" is undergoing the vk56 swap into a 240Z? Here's the link:
