Question for those who have used Speedmaster assembled heads or valve springs

Well this is not something that I am going to be shutting down during idling. Are you just trying to avoid valvetrain wear? Or is it because the pressures of the valvesprings are actually too much for what youre doing?

As far as the cam goes, the cam im sending for regrind is an 90s crane grind, so im thinking im good on the quality end of things in regards to the core.

Yea im trying to avoid going near any of that as a lot of those threads are conversation back and forth not really pertaining to the topic and take an eternity to find info lol.

I know you had mentioned before that you had a set of the assembled hydraulic roller heads for a customer, did iu by chance test the springs? Were they pretty close to the advertised specs for them?

I never test the pressure as delivered because I set them up as per customer’s wishes. I think it was JPar that said they were on the light side of advertised pressure. I’ll be tearing down a set of hydraulic roller spring heads today and I wish I could take the time to check some for you but doing it right involves measuring spring heights then pressure and I’m so backed up with work I can’t take that much time. I do know the last set I tore down had six hardened thin shims under the springs.
