KR Head on EX block????

[rwh1990]

Hey all,

Been having some thoughts on what I want to do engine wise with the rocco, and have a question for you all. Does any one know if a KR cylinder head will fit on an 8v EX Block?

I would imagine that due to the dished piston shape of the EX pistons and the larger dome of the KR compression would suffer, however should it fit, I had planned to fit high compression flat forged race pistons which should at least return compression to around the same as a standard KR, right?

I know it seems like an odd combo when there are soo many alternative swap solutions, but its something I haven't seen and would like to have something a little unique. I also want a relatively easy and build that still allows for a full top to bottom rebuild at home with out having to worry to much about additional parts / ignition etc to make it work. I plan to run it on Twin 40 / 45 carbs and like the way the KR allows these to be on the opposite side from the exhaust. Basically I want to keep as much of the original EX engine and setup as possible and keep as many things mechanical over electronic (ingnition etc).

Originally, I had just planned to fully rebuild the EX, take it to 1.9 / 2.0l, lighten, balance and knife edge the crank, forged high comp pistons, balanced rods, ARP bits, MLS headgasket, port and polish the head, fast road or maybe race cam, 4 branch exhaust manifold and fit the twin webers. But like I said, I like having the carbs on the front away from the exhaust manifold and imagine having the 16v over 8v might be nice too.

Forgive me if I sound like an idiot for even suggesting this as while i am pretty good with things mechanically and can happily rebuild things etc, I am still quite new to the intricacies of it all, the numbers and compatibility etc.

look forward to hearing what you all reckon!

Cheers!

Hi,

I might be wrong but as far as I know, no you cant.
I seem to remember looking into it a while ago.
A simple way to check would be to try and line up an 8v and 16v head gasket and see if any of the holes match.

hmmm... never thought of checking that way, can't believe i didn't think of that! gutted if it doesn't, it all seemed like a great idea in my head.

Cheers!
