Taller tires will work but all that will do is keep your RPMs down. Can't say how much it would cost you but probably the cheapest thing to do is to have the springs shimmed to raise the spring pressure. If you can pull the head yourself, you should be able to take it to a machine shop and have the work done for not much cash.

Thanks for the info. Since I bent a valve this past Saturday I just pulled the head tonight.I will check with a machine shop later today about the shims and a new valve. I did see some performance springs at escortfocus.com that would let the engine rev well over 6000 rpm. would shimming do the same thing?

Don't buy ANYTHING off of escortfocus! They're VERY overpriced, and lots of their stuff is junk!

Thanks for the info. I am working with a local shop on getting this thing to hold up for a minimal price. Starting with new stock springs and shims. Good luck on the sponsors dude. Sometimes U have to be in the right place at the right time.

I agree that Escort Focus is waaay over priced. You'd be wasting your money buying springs... especially from them. Have a machine shop stick a .020 or .030 shim under your springs and you should be good to go. Worked for me and I've got a super lumpy Ultradyne cam with a bumped up rev limit and I don't get valve float at all. Is it possible that you're not hearing valve float but hearing the factory rev limiter kicking in instead?
