enough retainer to seal clearance?

So I have measured out the clearance on my vortec heads using the type seals shown below and have come up with this.

The intake valves have 18/32's or .5625" travel before the retainer will hit the seal.

The exhaust valves have 16/32's or .500" travel before the retainer will hit the seal.

I have read somewhere that these seals cannot be ran on these heads without machining the guide boss. Is this true?

And if I can use these type seals will I have sufficient enough clearance to run an XE262 cam which gives .462/.469 lift.

Those are just stock replacement seals, nothing special.
If you have a few bucks to spend, have them machined for
PC type teflon seals. I think I only charge $40 to do that, so
a shop in your area should be similar.
