The key thing is they are narrowed at the stem at the bottom. Narrowed to the same diameter as stock 3X00 v6/60 valves. Personally, I will narrow my next set of valves even further.

The stockers are much closer to being a tulip head, which makes porting for those valves much different than porting for the updated valves.

What compression are you running, have you had problems before going to E85?

10.85:1 is my current compression but because the cam I have I must run a very aggressive timing curve.
I did not change to E85 becasue I had a knocking problem.
I changed because I want to have all the upgrades made before I install the new short block, 3.7 with Iron heads.
One thing I tell you, There was a 50 degrees IAT temp drop just by changing to E85 on this engine. 
Oh and now I can sleep at nigth knowing I'm helping the enviroment![This message has been edited by La fiera (edited 06-01-2019).]

The other short block with these heads will be at 11.58:1 exactly. So the E85 will be a big help!

Finally took my car out yesterday for the first time with the E85 upgrade.
It feels much different than before, more explosive on the gas, revs faster, winds out
through the gears much faster and the cam comes in with such a punch that now
the clutch can't hold. Even in 4th while cruising when I give it more gas and the RPMs
start to climb and when the cam hits the clutch slips. Still have tuning to do.
