For the W5 lovers

They will work with 59 degree lifter bank angles. If Brett Miller doesn’t have any I know Kent Ritter does. In fact I forgot I need to call him back.
Thanks. I have a 48* R1A w/ W2s. Be nice to have W7s on it. I had a pair of Chapman? ported heads years ago. Discovered they were junk. Ugh. Other than "alot" what do you think a setup would cost? Just getting options before I either fix my 340 or get my 380 back together.
