Hey guys I am looking to get some descent heads for my 355.

Zero decked 355
Flat tops with valve releifs
Exact specs,
Crane thumper cam...
Adv/Dur: 287/305
Intake/Exhaust Lift: .489/.476
Q jet and performer rpm intake
I have 882 heads right now and they suck
done too much work to this motor to have such shitty heads on it.

So I am looking at...

World sportsman IIs (cast)
Edelbrock E-tec 170s (alum)
Edelbrock Performer RPM (alum)
Patriot Freedom series Strait plug (alum)

All are just under 900$ for the pair, all are 62-64cc.

Thanks in advance guys.
