is it worth it to buy aluminum headsfor my 85 camaro (how much horsepower) I am taking the stock ones out tonight to clean them before i install the intake and carb i just bought and if it is what are some reasonable priced pair of assembeled heads. i found some on summit for $660 which i could save up in a few weeks. any one have some that are in fair condition i would be interestred in. thanx justin

 

Aftermarket cylinder heads are always a good performance gain, but how much depends on the rest of your combo, with a stock cam and exhaust manifolds the change will not be near as dramatic as with headers and a good cam. I see that you now have a 305, make sure you buy heads with 58cc chambers so that you will not lose any compression.

 

Keep your stock 305 heads. Put on better valve springs when you have them gone through. With cam, intake (and I hope you aren't taking off the stock q-jet - best street performance carb system out there), and exhaust, that will do all you need until you go to a 350. Even then, the heads will handle a 350 (as will the stock q-jet - it's the best street performance carb system out there).
