How good were these new pushrods?

Did you check to make sure there was no clearance issues with the pushrods and heads?

I had a set of EStreet heads come through the shop a year or so ago......had waaay too tight guide clearance.
edelbrock heads in general have less guide clearance than I prefer, but this one set was particularly tight.
It was because of the stem diameter in that instance.
Edelbrock seems to prefer the valves be .0005(half a thou) smaller than what typical for the industry.
.3410 is "normal", Edelbrock likes to use stems that are .3405, and they set the guide sizes based on the valves being .3405.
This one set of E Streets had valves with stems that were .3410....... so the guide clearance was .0005 less than normal(for Edelbrock). The intakes had like almost no clearance and the exhaust were about .0006.

The only way to know whether they're good or not......is to take them apart and check.

However, since it's all together, if the new pushrods are at all questionable......I'd change those first.
