Does anyone know what the factory pushrod length is on the non-DOD cylinders, 7.850"? Assuming I were to use a new GM same thickness head gasket, Cadillac race lifters, and a Cammotion Titan II Cam, would I need a pushrod length checker to verify the length or would measuring the stock length pushrod on a non-DOD cylinder work? Will 3/8" fit or do I need to use 5/16"?

My plan on a 22 1LE M6 is as follows:

1. Rotofab CAI with dry filter
2. Katech ported 87mm TB
3. Non ported LT2 intake
4. Cammotion Titan II at 222/234, 114+4, .612 .603
5. Cadillac race lifters
6. 1 7/8" headers with cats to stock NPP
7. Get a Tune with HP Tuners
8. DSX Flex fuel kit
9. Will normally run on 94 Chevron or 93 Shell

Everything is pretty mild, but put together I am hoping for a very reliable 510hp or so at the wheels on 94 Chevron. What do you guys think?
