Small Block Chevy Vortec Cylinder Heads
Specifications:
I just bought a set, I am spending good money to have a friend help me install them, it shows the center bolt valve covers will not work is this correct, please let me know i need my truck back, wife wants her car back. 98 chevy silverado 5.7 vortec .
What is the spring tension on these heads? Can you run hydraulic flat tappet liters in these? Do they have double springs and do you need to remove one to break in cam?
What is the max lift on these heads
Is their an airgap intake you can recommend for these heads on a 400 sbc
Since these heads come with guide plates do you need to use self aligning rocker arms? Or you could you use regular rockers and take the guide plates off? I have been told to run one or the other but never both
If running a vortec intake do you need to plug the center holes for oil seepage??
Will p/n 2151 work with Edelbrock Performer intake manifold for pre-'86 SBC? Or would it be better to buy a new Performer manifold for Vortec heads? What p/n springs can you recommend for hyd roller cams? Thank you.
I tried using a 1205 gasket and a team g intake the intake and gaskets don't cover the top of the intake runner there is a 1/6"gap at the top of the runner but a vortec intake covers the runner
