so you have one 243 head and one 241 head installed on the car??... was the tune adjusted after you swapped heads?

You aren't going to get much hp gain on stock heads, especially when the cam isn't designed for it. I wouldn't waste time on a retune until you get proper heads.

do a compression and leak down test... add headers and get it retuned

This picture is a straight up install. If the motor was rotated before the timing chain was installed then the cam will not open the valves correctly.
