I have always been using Fel-Pro #8180PT2 head gaskets on my 454's
Regarding springs, go with the Iskys.I think they are way better than Crane.

The 525sc has a flat tappet hyd. cam. You can look up the parts at www.cranecams.com. The cam is pretty mild and the Crane valve springs last a long time. I've had several engines with this cam and never had a problem. My last one had 600+ hrs on them when I sold it.

Glad some of you had good luck with Crane, I just broke a valve spring at 30hours. This weekend I'm installing the Comp 929 springs. Hopefully they work out better.
Do a search on the Subject. Unfortunately Crane valve springs don't have a good reputatation in IMHO.
Felpro gaskets work good. Felpro intake gaskets can be a little big around the water jacket, make sure you get the right gaskets for your application.
Good luck

Patri yacht,
The Crane springs that broke at 30 hours are the new design. I probably got the set that was made on a late fri afternoon .
plus it damaged my rocker arm. I have switched to Comp 929 springs with the Comp Pro Magnum rockers. Hopefully these are going to last.
