Hey guys...

Just a question..I found a great deal on 04 Cobra cams/springs/retainers/ all brand new for a really good deal..I know they will fit into the B-Heads..but will there be enough valve to piston clearance with the stock valves....and there won't be any hitting of the valves to the pistion????? Anyone got the lift/duration of the 04 Cams???......and what do you think the power increase would be??? thanks for the help!! BTW..these will be going in a fully port polished heads..

I think you probably will have piston to valve clearance. I would contact one of the premier modular builders and ask them on advice on engine build up.
