had some head questions, i have a 350 block that needs a rebuild and has never been rebuilt, hydraulic rollers, 89 model block, i am using the eagle 383 kit with the flat top pistons, and if i use 64 cc heads it gives me a 10.7:1 compression ratio. i am building this for street, once in a while strip. here is a link to the heads i am looking to buy, are these overkill and will the fact that they are aluminum help out with the higher cr? or should i go with some larger cc heads? open for all opinions.
