Are the 906 vortec heads any good? What will I need to do to them to put on my race motor.

Very good Chevy head!

They don't come stock with screw in studs & you will need an intake made for Vortec heads to name a few things...

are you running flat top pistons or domes?

Thanks Ruggs!

I run a 2 valve flat top an a 4412.And already have the intake from power plus.

Will i have to change springs for the big cam?

Oh yes,

you will need springs to match the cam.

The company that sold the cam will know what pressure valve spring you need.


Most Vortec engines actually have small lift roller cams less than 450 lift stock.
