Default lt1 questions?

Ijust bought a 1994 lt1 with a bad engine , so we took it apart , it has aluminiun heads , does all lt1 came with aluminum heads?
The camshaft has a number #970709, does anybody know what time of cam this is , looks like a stocker but i'm not sure,also the clutch is a valeo clutch kit , are those any good?, should i put the same one cause i'm shooting for 360 rwhp with my new cam and port job

Aluminum heads came on Camaros, TA's and Vettes. Iron were on Buick, Impala's, Caddys...

The lift on a stock aluminum cam is .450/460 with 1.5 so measure it if it is different you know it is not stock the same delve deeper.

360 RWHP will be a reach...you will need head exhaust, cam etc

Good luck
Jack
