Sleddog brought up a good point about stainless steel valves. He's used
stock valves in 385 series street and performance engines without any
problems. I've used the stock valves in different sets of 385 series heads,
including the CJ, with no problems. Mine was/is street usage but I run them
very hard.

I've asked other lists for the advantages of SS over stock valves for street
applications and never really received an answer. I do know that they
provide some increased flow over stock due to undercutting the back of the
face but am still curious as to whether or not I've been, once again, caught
up in another slick aftermarket promotion. Lots of companies make stock
valves but only a few make the SS and they do advertise them. Any advice
will be appreciated.

I don't know the science of it but from a strictly metalurgical stand
point stainless is softer, tougher and more tolerant of vibration
than hardened tool steel but tends to work harden and become brittle
more easily in my experience. The main advantage I see is in
corrosion resistance and toughness (abraision resistance) in the stem
and valve face. Right now I'm not sure if heat sinking is any better
or not but this may be another factor in it's favor.

Some stainless can be hardened but AFAIK not to the same degree as
alloy tool steels but even soft it's tougher than tool steels. Keep
in mind that one of the main ingredients in stainless is chrome which
is a very tough material.

Watch him guys, he'll be another Bill Gates before you know it!! You
wont be able to buy anything Ford Truck related without paying him a
royalty!!!! Next thing you know we'll have to call him sir!!!

Lord help us all!!!!!

The 30 deg seat makes a lot of sense for any engine that wont be running
sustained high rpms. If you have a well tuned intake and exhaust tract
for your appplication, it will give that extra low lift flow that can
make the difference.

Short track circle-track guys use them to get off of the corners
quicker, and the difference can be pretty dramatic. Think of how much
time the cam is spending climbing to and declining from max lift. The
more air you can pack in these periods the better.

That's why alot of engines are better running than their design would
merit, their low lift flow is better and pack in more air over the
entire stroke.

You guys are beginning to convince me that 30 degrees is the way to go. I've
been looking at cam profiles and it looks like 6000rpm is a realistic goal
for what I'm after without sacrificing, thanks to cubes, the small runners
and big valves, too much of the low end torque. How does the 30 degree seat
measure up to 45 for normal highway driving?
