That depends on your cam. If they don't have notches in the pistons then most likly no they won't clear but the only way to know for sure to to check with some clay or playdoh.

TFS TW heads provide more clearance over the stock inline valve design (stock/aftermarket) due to the valve's steeper angle when used with flattop pistons. Obviously, to a point.... knowing more details of your setup would help. LUK

WITH any set up, op you should always check ptv using the proper tools and techniques

Like mentioned above, the only way to be sure is to check PTV clearance. My 302 is a perfect example. I have a stock bottom end, with Twisted Wedge heads, and my cam has a gross valve lift of .569 (custom CI cam). I don't have any issues with PTV clearance. The valve timing events machined into the camshaft affect PTV clearance just as much as lift. That's why it's important to degree the cam per the manufacturer's instructions.

Most likely not..... but that doesn't mean you shouldn't check.
