What do you want to do with the car?

sorry its a 302, im just wanting to keep the bottom end stock, everythingtop endaftermarket, eventually run a smaller supercharger

165's with the optional blower/nitrous exhaust port would work nicely. If you're not afraid to add some better rod bolts and turn some rpm, a cam and 185's would work nicely as well.

why not look into the new edelbrock 170cc heads? they are supposed to flow as good as the 185's yet have a smaller runner. seems like a great "in between" head, maybe better (unless your going to hog out the 185's later)

Where can you find these new 170cc Edelbrocks? I havent heard much about them.

AFR 165 for the stock pistons.

AFR 185 for aftermarket pistons.

I hate to see an AFR 185 head used on a stock bottomend with a camshaft "tailored" around the clearance.

With the "larger" heads, you are not going to see anything unless you have an intake to keep up with the potential.

For example, there is not need to have a 280 CFM head, if you have a 240 CFM intake sitting on top of it.

165

You'd have to call Edelbrock about the new heads, they list the flow specs on their site, and they're listed as an option in the power package section, but that's it. They'd make excellent n/a power, and work well with a blower as well. If they have an optional larger exhaust port they'd be great for a blown setup.
