Porting 853 heads? How much of power would i gain if i ported my 853 casting heads on my 99 camaro with a pretty big cam and would it be worth it? The heads were rebuilt about 2k miles ago

You will see a little bump in hp from porting, but remember the 853's are the Worst heads out there. If you are on a budget save that money get some 243's and have them ported. Much better results.
