I’m building my rb26 head and looking at springs.  I’m not very knowledgeable on heads and looking of insight. I already have tomei type b valve springs and retainers and curious if they are up to the task for eventually 30-32psi of boost or if I’d run into valve float?  If you have another suggestion for valve springs and retainers I’d be interested to hear it if you’d kindly explain why.

No, the Tomei type B is shit. Their seat pressure is pretty low for high boost. I had them, nothing but problems.

You want 30psi+, I think you'll find everyone will be recommending Supertech valve springs. Much higher seat pressure, very good stuff 👍
