If your heart is set on GM production heads, then I'd go with a "Phase 2 Bowtie" for cast iron (part # 12480034 or 12480053). I'm pretty sure these heads have the stock port locations so conventional intakes will work fine. They've got plenty of room for porting, but intake cc comes at 184. They are also machined for screw in studs and guide plates, and are available bare for around $290.00 each. Scoggin Dickey has them assembled for $548.75 each. (Not too cheap for cast iron)
For aluminum heads the only choice is the "Fast Burn". They make tons of power out of the box and can be ported further. They sell for about $585.00 each complete. Part # 12464298
Hope this helps

My Memory banks don't work so good any more, but I seem to remember an artical in Hot Rod concerning the vortec heads and an Edelbrock intake for carbs that will bolt to them. Torque and HP was very good as I remember.

May check the library for back issues.

550 plus HP/Torque? With '88-up GM fuelie heads? Can you say aftermarket? Pro Topline, Dart, World, Brodix, Holley, Edelbrock, AFR, and many, many others make what you're lookin for. GM does make the Bowtie, 550 HP maybe. But the Vortec? If you like takin your chances with thin castings, good luck. GM does make several aftermarket aluminum heads that are top-notch, but pricey. Take a look at, or

The vortecs are a little thin BUT the pro topline version is beefy and looks almost identical to the stockers.
