hello, Id like to know what are the best aluminum heads would be for my 305. I have a TPI 305 LB9. It has the original heads on it. I am keeping the factory cam and factory lifters I dont want to change this. I would like to put a high flow set of heads on it and some roller rockers and thats it. Maybe leave room for the high flow Edelbrock TPI setup down the road. So what are the best heads to get so it will work with my computer and stock set up and improve performance. As far as chamber size and port size if people can tell me some more about that. thanks everyone

 

The World Products SR Torquer 305 heads are a direct interchange. You will need a head with the small chamber size found on the 305 (I think it's 57cc) or you will lose ground due to a lower compression ratio. Good Luck!
