Vortec head ????? after using search?

[SY2455]

I have the chance to get a set of Vortec Heads free that need rebuilding can you on the list help me with the following ?????s

1. These heads are off a 94 4dr, 4wd blazer with the CPI intake & plastic valve covers that got damaged in a fire. After I get them rebuilt, can I install them & run without any changes to the computer & chip?

2.Will the heads help with the occasional ping I get because the gas varied from tank to tank?

3.If I must make changes, what changes are neccessary to keep the truck dependable & reliable like it is now?

4.Can you list the parts & best place to buy them?

Post the casting number of these heads. I'd say if they are from 94' they are L35's and not Vortecs...

Later,

If it's a '94 CPI, I believe that's the L35 motor. Which is a direct bolt-on in place of the stock heads. The L35s are better, but not as much as the '96+ Vortec heads (which require modifying the heads and/or intake). I couldn't tell you if the L35s are different enough that a chip change would be required.

But if you bolt on these heads after rebuilding, Can you use the stock chip??
