KR head on a 9A Block...

[Akinesis 0]

I'm sure this question has been passed around quite a lot, so apologies for this.

 

I have a complete KR engine sat in my garage and I've heard of people fitting the KR head onto the 9A block :norty:

 

I know the KR inlet camshaft does wonders to the 9A but how about swapping the entire heads over? Is it better than just changing the cam?

 

Many thanks all :grin:

not really any difference, minor changes to the inlet ports,

general condidtion of heads is more important.

Cool! Let me know how you get on! How come you're doing it - for the power gain or just because the old 9A head was tired?

Dont know thb. Assumed it was cracked, not had it looked at :lol: A KR head come up for sale on here so I went with it. I did manage to get a stainless 4 branch to so it should be a nice valver I hope

as already said,just get hold of the best condition 16v head you can find. 8)

I'm running a kr head on a 6a bottom end.(same as 9a) simply because the components were available to use.It's what you do with them that counts. 8)

Ok, cool! Will keep the 9A head on and just swap the inlet cam over :salute:
