Have your friend go to
www.enya-engine.com and write Ken Enya an email requesting the particulars on that 80-4C cylinder head. Ken is usually fast to respond and his prices aren't bad either.

BTW, the conclusion to all this is is that I got him a Phoenix Decathlon (.46 size, really, really nicely built ARF too) for his birthday, and it is sitting under the cowl as I type at about 15 degrees from inverted, with the muffler routed out the air outlet. Layout worked perfectly. In the meantime a few break in runs proved that it is a strong, smooth runner.. come springtime we'll find out how it all works together.
