Who do I name drop?
Most guys don't want to buy custom valves or cut down a bigger valve. That was MY point.
Bullshit. Many people don't use nailhead valves in everything. Ive got 4 cylinder stuff out there with 50 and 55* seats and ALL of them get tulip valves.
I'm not getting paid to educate you on how to do steeper than 45* valve jobs so you can figure that one out. The steeper the seat, the more the valve wants to wedge in the head.
I'll say it again, I don't like back cuts on much of anything, but the width is not important. The angle of it is (most guys love a big back cut because it looks good on the flow bench) not important, as long as the back cut butts against the seat on the valve. That should be easy to understand.
I offered to flow his head for FREE. And I would not have just flowed it at one pressure and sent it back. I also offered him a cam I've used and know what it does. Did you want me to drive across the country and pick the heads up? He would have learned more from my flowing the heads that just paying someone to test at one pressure.
What do I regurgitate? If I was regurgitating I'd agree with all the goofy **** you do, like opening the LSA when mid RPM power is down. If he has a reversion problem that is about 1800-2000 RPM no cam, not even the wide LSA will fix it.
Come on dude, get over yourself.
