The motor in my 78 camaro was a 1988 TBI 350 out of a chevy truck (195hp). It has an Eldelbrock manifold and 600cfm carb and 1 5/8 headers and 2.5 inch exhaust (So I don't know what I have for hp now). Intake valves on these motors were 1.84 not 1.94. Other than this, motor is stock. This is a non roller motor.

Now, I have a chance to purchase a set of 062 vortec heads with after market manifold for a good price. If bought, I know there are other things that need to be done and checked first. BUT, If old heads were taken off and vortec heads and manifold put on, is this a straight swap? If not what else needs to be done? Can same push rods be used or are they the wrong length?

What would I gain by going to these heads?

 

The pushrods you have on your 1988 TBI are the right length.

 

Your going to gain some good HP and TQ. Your biggest down fall will be the small stock cam shaft of the 88 truck motor. If you could do a cam swap when you do the heads you could use the full potental of the vortec heads. Best upgrade for a set of stock uncut heads is the Comp EX-268 cam.
