Tony,
You are a strange fellow. I can't understand, nor do I listen to the Flies on the wall.
Billet, Epoxy, Plexiglass, Wood etc.. ALL LEGAL, but maybe NOT GOOD for a V4F head!!!!
No Worries Tony. Count the Hours before Post.
Thanks,
Mike
PS: What V4F engine are you building? Send some pics my way. E-mail is in RB.
