Are these heads pretty good, do they offer better performance then stock l98 aluminum heads. I know they are cheaper then buying the zz4 heads which are the same as stock l98 aluminum heads.

Those are cheap because they're bare. Price up everything to assemble them and you've got a pair of expensive 165cc heads.

Litlte better than stock (dont expect much) , they need work to run.
Good for a stock replacement though.

Save more and get a good set

Upgrade to a 355? Do you know what you're talking about exactly? =\ I won't even get into detail on that..

There are numerous well-known brands for heads to choose from:

- Edelbrock will offer the basic style heads with generally the same flow pattern as stock with slightly bigger CC and runners.

- Dart makes excellent heads in both CI and aluminum, and they have a great selection for what you'd be looking for a good price.

- Brodix has, IMHO, one of the best selections of heads you can choose from, and they will also mill the CC to any size you desire for a little extra. Some are more costly, but all of them will carry their weight. And then there's..

- AFR.. one of the most controversial companies on the forums. I won't get into exact details on that, but they boast THE best flow rates for their size runners, and some great low-RPM numbers for the range of cams they've run in their testing.

There are other brands that make heads as well, like Patriot, Summit, etc, but these are some of the more popular, and reliable, brands to choose from. If I was you, I would sit down and decide where this build is going, and choose the exact head that will support your target numbers.

I picked up a used set of heads ($650.00 pair) in the parts for sale on the forum. The heads are the rpm performers. They have the 70cc comb. chambers and 170cc intake port. I've ported the plenum with the intent of adding large tube runners and hi -flow manifold in the future. The original heads were the 624 cast iron smog heads.
I've been happy with the Edelbrocks and have added 2-10th's to my et. currently 13.65 They'll work will with my long range goal of building torque and thrashing Mustangs. If youre looking for high RPM's the Edelbrock head is probably not for you.

I bought a set of those Edelbrock heads fully assembled. Perhaps not the best heads you can buy but I did notice a nice bump after installing them. I took a good look at them before installing and they can be ported if need be.
