Your Opinion and Suggestions please.

I've foudn the bowls to be ok out of the box. The exhaust guides are too tight for my taste, and the small amount of taper they leave at the port openings is nice to remove. I blend them back about 1" into the ports, and that's it. I wouldnt enlarge anything for what you want to do with the engine. I would also be very careful in regard to valve springs. "Works with cams to .600 lift" is a misleading statement. I've had to replace springs on 80% of my builds using Edelbrock heads, because what they include would be maxxed out with some cam choices. I prefer to run a little more spring so on street engines they last longer. And you base spring choice on the lobe shape much more tha total lift. As an example, running a douuble spring instead of the singles they have, so the spring is operating at 70% of capacity as opposed to a signle spring operating at 100%. Also, I agree with BJRs cam specs at .050. But I would keep lift in the .580 range for solid rollers, and .550 in hyrdraulics. Personally, I'll run a solid flat tappet before i run a hydraulic roller. If someone wants a roller, go solid and prep the block for it.
