Do you think this combo will have piston to valve problems?

First off I will check it out, but want to know what you guy's think.
.030 bored stock block with flattops, comp XE264HR (.544 lift w/1.7's, 212/218 @ .050 114* lsa). With E7's milled .035"
Think I'll have piston-to-valve issues?
What about springs? I know stock wont work but can I get a spring that will allow that much lift on E7's?

I got 544 cam and 1.7s too. Experts help please.

P to V clearance shouldn't be based entirely on the max lift of the cam. Duration is also a big factor (how long the valves stay open). In your case I would GUESS that it wouldn't hit....but the only way to know for sure is to check.

Duration is closest at 10 BTDC, It also depends on your flat top as far as relief depth etc, you shouldn't run into any radial clearance issues with the small valve E7.
