is the tpi system a good choice to install with ZZ4 heads and a zz4 com cam?

 

If your CR ends up the same. ZZ4 heads makes your engine the same as a Vette L98 TPI with alum heads.
ZZ4 cam worked great for me but likes intake mods; big tubes , ported plenum and base to get the best out of it

 

what intake mods and parts do you recommend? My intake is stock right now

 

As I listed .A aftermarket big tube setup or port your own

You said if my CR is the same I'm a beginner at this can you explain this to me?

These are the heads I wanted to put on my 1990 Firebird 350

CR = Compression ratio .Heads have different sized chambers .
I believe L98 w/ iron heads is 64cc so the 58cc head will raise your compression somewhat

Also consider
Needs new intake to match but it is a big port intake saving you having to do the intake mods
