Hi guys, might be looking at Ti 2.08 intake valves to upgrade my dart heads.
Which supplier, also looking at lighter springs possibly?
I have dual golds at the moment, but want to rev nearer to 8k, and valve float is setting in around 7.4K at the moment.

Xceldyne and Del West are probably the two most popular brands.

What rockers are you using? I would try springs before pulling the heads if it was me.

Standard rockers, i tried roller rockers and they were rubbish, valve float at 6200rpm with those!!!

I use REV Ti valves, quick turn around, easy to make changes, haven't had issue.

I've never seen a hyd. roller LS engine go to 8000rpm that didn't mean to

Need the right camshaft for that application, with Limited travel lifter or SR.

What height did you have gold springs setup at?

Is there a reason you want the extra RPMs? As in trap, power still climbing, etc...?

Awesome car lstvr I always loved the Cerbera and you have made the best one on the planet!!

Yep, 3rd gear is just on the limit as i trap at around 133mph, and i have the biggest diff in that they produce, also 202 is at max revs too, went up a tyre size to go from 199.99mph to 202.00.
Theres an event here and 208mph is the record, wouldnt mind stuffing it up the RUF 911 guys and have the title!
