Default TRak cam, ls6 heads, what size pushrod?

I am finalizing my setup and need advice. Anybody with the trak cam, what size pushrods are you using? Also, the valves on the 243 heads are the sodium filled kind, they are just a little bit longer.

My setup is going to be:

- TRak cam (231/234, .640/.590, 112 LSA)
- AFR 8019 springs
- Titanium retainers
- Hardened pushrods
- LS7 lifters
- MLS headgaskets
- Stock LS6 heads, off of 02 Z06 (lightweight valves)
- stock LS6 rockers

You need to find out how much longer to find an exact pushrod length. Then subtract that from a stock pushrod but add back in the difference in base circle on the new cam. This also assumes you are running OEM lifters and want to run stock preload.

I am running OEM lifters.

I got this information from one of predator's responses,

LS6 valves are .0236 inch taller to compensate for the smaller base circle of the LS6 cam. So .0236/1.7= .014 smaller radius. (extra length p-rod needed)

Anybody know the base circle of this cam? Also, pushrod length is the same on LS6 vs. LS1.
