Seems a little slow...

Your pump shots are way too small.
35 front and rear too start.
Wait until you hit the gas.
It will be a hole new car.
Every tenth you gain in 60 foot adds up to about two tenths at the end of the track.
If you can gain two tenths 60 foot, then you should have four tenths on the top end.
The 1 5/8 header is perfect for your motor.
The 727 will slow you down a little bit but on the other hand it's very strong.
The 904 has a lower gear and is faster off the line.
The reason i said the 1.6 rocker was over kill was that your lift will be around
.563 - your lash setting.
Going off your post you use a .026 lash setting and that comes out to .537 lift.
It really isn't a big deal, but if you had the heads flowed you would know where your cut off point would be and run the lift up to that point + the amount the lash.
What's the lsa for that cam?? (center line)
