yes, unless you have Twisted Wedge heads. I had Windsor Sr's on a stock bottom end and had to flycut to clear a B-cam (.480 lift) on the intake. Exhaust side cleared fine, the edge of the valve hits just above the eyebrow. I have heard 1.94 is the biggest intake valve you can use on a inline valve head, I know my 289 heads with 1.94/1.60 cleared with an E-cam (.498 lift) with no problem. hope this helps...
