need some advise - lysander engine fit - those who have faced an issue like this

I recently did the Eduard release of the Lysander, and I had the same problem.  I actually lopped off a couple of the cylinder heads to get the engine to fit into the 3-part cowling. It was still a tight fit, but it's not really visible as to what I did to get it in there.  Your solution will likely work as well; I think I went for the easiest solution given how hot it was at the time I was building my Lysander.

Can you gently chuck it in a drill and use a sandpaper block to evenly take off the tops of the cylinders?  I had to do that for a 1/32 IAR.80.

thanks both!  im afraid to try and do anything now with the cylinder heads seeing as its all glued up.  If i did, i think id have to bust em all up and re-do.  Think im gonna try to squeeze it in and re-do the seam....  If i had seen this issue earlier i would have sand them down but like i said,  i missed th dry fitting.  Next time ill tape it 1st

ok, so the gap is bigger than what i was thinking.  But, done for now.  We'll see.....

This is a common problem for me when working with radial engines.  I use a flat needle file for removing the top of the cylinder heads, little by little, a few mils at a time, going around the engine.  Never failed to get one to fit.  Usually with cowl in the butchering of the head is not noticable.
