For $89 more..... I'd just get some E Street heads.

In fact...... That's exactly what I did.

For me, the Stealth head is a budget head for those who really want/need the straight plugs, and/or the OE type appearance.

Between the RPM/Stealth/Sidewinder heads, I find the Stealth has the weakest exhaust port....... And the Sidewinder is the easiest to get to 300cfm on the intake side(IMO, it has the best short turn of the 3).

The RPM/E street is American made(a plus to me), and has quite a bit more room around the intake pushrods, so 3/8" pushrods and 1.5 rockers usually fit without any clearancing.
