Interesting from that the Leo & lw2 are identical!
Sort of on original topic I don't suppose anybody has a set of LY7 heads lying around & willing to sell?

Re: Alloytec Cylinder Heads
Correct me if I'm wrong but isn't the Leo twin vct and the ly7 quad vct?
So the ly7 should have bigger valves.

Re: Alloytec Cylinder Heads
All that I can tell you is in the vz the 190 has slightly larger valves to the 175,but you can't swap them without Kline the guide cause going by the measurements they made the stem on the 190 smaller.

Re: Alloytec Cylinder Heads
LOL not sure what you mean by that bit at the end?
According to what you posted on each there all the same except the LF1?
But then I think your saying another reference was saying the LY7 were larger?
