I stumbled across some really nice un-cracked magnum heads for this project so I will be porting them and milling them as much as possible... What do you guys think of sinking the valves in the magnum head a little so I can mill it more??? Would say .050 down hurt flow or anything? Seeing how the intake valve is the limiting factor for milling it more this would allow a little more milling to further reduce the chamber size and get some super size compression going in here. I could shim the springs or maybe run some LS chubby springs... what else am I missing with this idea?
I don't think I would sink the valve. I had small chamber W5 heads and they were the same with the valves very close to the deck. I had them shaved down to the seat so the intake valve actually set below the deck surface.
