Hey i got a new setup of heads today. Not sure what there from but it a v6. Will the cast numbers tell me what its from and where can i look them up? Reason i gotem was to practice port and polishing.

 

do you know what make they are???

 

No, theres no manufacture logo or anything on them. They just have the number and made in mexico on them. Which i think chevy's are assembled there but not sure.

 

The Casting # is 10218170. I googled it and info came up on the chevy 3.4 v6. Can someone help find out if these will fit a 1992 camaro 3.1 ? Thanks!!!!

 

They will fit, but to practice porting they are a completely different design from the iron heads. You will need to use FWD pistons or you are going to have in the neighborhood of 12:1 compression.
I also have a pair of 170 castings that will be going on my next motor, you will also need to get a 3400 lower and upper manifold along with the fuel rail to use them.

 

ok, i just got these heads for free, just wondering what they went too. I think i'll still port these just for the practice and experience. Thanks

 

I'll trade you a set of stock iron heads for those aluminums...

 

Their pretty rusty by the valves and not sure how good of condition they are in.
Whats the condition of your heads?

 

If the valves are rusted, tht's OK. I would hate to see you ruin a set of high flow aluminum heads just to practice porting . The heads I got are pretty rough (rusted, brocken studs, etc), but if you are just wanting to practice they will be perfect.

If you do a search for porting heads here on TGO, you will see someone doing something similar with heads just as bad. Even though the thread is for a V8, the suggestions and pics will be helpful.
