1971 LT1 heads 75cc??

Does any one know if these heads are any good I had never heard of the 75cc head but they were rated at 370 horsepowe. How well do you think these would do on a 383?
Thanks

i don't know the cc of the lt-1. but they came with 11:1 pistons so they may of had a larger chamber to make room for the piston dome. you can always get a little milled off them if you need to reduce chamber volumn.

Met,

Get the casting numbers from inside the rocker area, then check for specifications at Mortec.com

I already checked the castings and that is what it told me that they were 75cc heads I was wondering if they would work well on a 383 with 10.1 pistons?
Thanks

heads are not given a rated hp nor is a 1971 LT1 a 370hp engine.
