Ok I Need To Know What Years Had The Aluminum 113 Heads For Sure I Have Read Some Posts That Say My 87 Shoulsd And Others That Say Not. It Would Be Nice To Have A 1 Word/# Answer Unless You Have Somthing Valid To Say About The Situation. I Would Also Like To Know What Gaskets To Use If I Have The 113 Heads.i Researched This And Could Not Come Up With One Solid Answer On Either Subject.

128 heads are aluminum, so 113's. What does the magnet prove?

I Know They Are Aluminum My ? Was Are They The 113's. So The 128 Flows Like ****. I Am Looking At Edelbrock 60879 Whickh Say 165cc Port Size And 65 Cc Chamber Size. I Know These Are Good Heads And Flow Good But Is There And Experience That Would Tell Me Not To Go With These Heads. Should I Go Bigger. I Am Looking For A 350 Hp Streetable Car .

The 113 heads did not come out until 1988. There is not a big difference between the 113 heads and the 128 heads, the exhaust on the 113 heads is a little better.

The Edelbrock heads are capable of supporting 350 HP if the engine is built correctly.
