Well I have different heads etc..., Your cam has more duration than mine which makes the valve stay open longer.

I had .132 clearance on the intake valve and way more than enough on the exhaust valve.

I had my cam custom made for my motor. The guy told me it would clear and it thankfully it did.

Good luck,
