Default PLEASE HELP! looking at aluminum heads

the crate engine in my vette has 76cc chamber heads, and pumps out 250 hp stock, and i have ~8:1 compression. i've modified the engine though.
i found a nice pair of aluminum heads that came off of a 1988 corvette, and it has 58cc chambers. would these work on a gen I crate engine?

thanks

Yes, I have a pair of heads just like them you will need center bolt valve covers but can use the old style intake.

Are those '88 heads, the so-called camel humps/mickey mouse heads?

What performance gains were there/are there to be expected?

There are two or three types of L98 heads out there. The major difference is exhaust ports. The D-shaped port is on the later model and is suppose to flow better. Also, make sure to have new bronze guides put in, they will last alot longer.
