Installing Victor Jr Heads

[Code Red]

I've that valve clearance is an issue.  Is this true?  Do you have to notch the 302 stock piston in order to use the Victor Jr. Heads?

those heads have the 2.02 valves right? Im sure they do so you better check your PTV clearence more than once. As long as you have valve reliefs in your pistons you should be ok.

Honestly, I'm newbie to this stuff but the Edelbrock spec sheets shows:
The valve size: Intake- 2.05", Exhaust- 1.60".
Will I still be ok? This is probably a dumb question but I trying to learn, "do stock pistons have reliefs" ?
