hey guys, im looking into getting a set of heads. right now on my motor, i have 883 heads. i have heard bad things about this head. they flow like sh*t and i also heard they tend to crack. so what im asking is what would be a good set of heads for my motor? mind you, i DO NOT know the compression of my motor. and also, i DO NOT know what pistons are in my motor. i will have to take my heads off now to find out what pistons i have. i was looking at a set of World Products Sportsman II heads. and my friend has them on his 327 and they make very nice power for that motor but im just looking for some suggestions for now. thanks in advance guys.
