I'm not a huge fan of swirl port heads you might want to consider vortec heads. Since this is not a roller engine block you might want to go with a this cam and 1.6 rockers.

The intake is going to be your choker. I didnt see if the profiler heads are 55-85 intake center bolts or 86 up. If they dont line up elongate them. The only high flow base still made is the edelbrock, the tpi big mouth was just a clean up eddy casting. The accel bases are harder to find. Best bang for your buck is sell what you have and let the engine breath with a hsr. Or if your on a tight budget start hogging the stock base and do most of the work on raising the roof of the ports.

Just that base will cost you more than the Stealth Ram. You could sell what you have and pay for the Stealth Ram.
One of the worst reasons for using something is because you have it.
