Hey, my car has been leaking anti freeze into my heads so I am going to have to get that fixed. I figured since I would be getting it done I should throw some new heads in. What would be good to put into my 89 GTA Trans Am 350. One more thing is there anything else I should get done while its apart?

thanks guys

Well, if you have the green, while you have the engine apart, why not go that xtra step and do a rebuild?

 

If the bottom end is still solid, I would get some vortec heads and the scoggin-dickey vortec TPI base. Even with the stock cam on a 350, you should see 50hp +

Just my $.02
