It would depend more on the intake, cam, and exhaust. What do you have?

2.02 intake valves WILL hit the stock pistons!

Depending on the cam specifications, it may or may not hit.

I like to see them used with an aftemarket piston, so the camshaft does not have to work around restrictions,as the widervalve radial clearance issue.

The head is not to big for "streetability."

finally people are realizing you can run theese heads on a stock bottom end. Im running 2.02 vlaves on a stock bottom end without notched pistons at .569 lift with tons of PTV clearance. It all depends on the design of the cam

yeah its a jay allan cam. Its great, it idles fine with a nice lope and makes great power. Its more expensive than an off the shelf cam but i wanted to get the biggest camI couldwitout having to worry about piston to valve clearance
