So I'm thinking of buying fresh 306 short block complete with forged pistons. What should I look for when checking it out? never really bought a used engine before. He's also selling some brodix heads. Should i go with those or some trickflow,victor jr or AFR's heads? Any info would be great thanks in advance guys...

Be very careful and wise when you buy a used motor if that's the case/if brand new then its all good, spin the crank shaft and make sure it does not travel past the deck of the block,ask for receipts,history on the motor, scratches on the cylinder walls etc, i know there is a few things i am forgetting so hopefully somebody chimes in also to give some other tips, i have heard of ok things about brodix, best bet would be trickflow and up on top AFR'S, good luck with the purchase and build bro, hopefully everything turns out well and you dont have a bad experience like i did, but you live and you learn so hopefully i kinda helped a bit from preventing this from happening to you, keep us posted bro...

A set of AFR 165's or TFS would both be nice choices if you have the cash. Just about anything aftermarket is better then some stock E7's, GT-40's/p heads.

If I had to pick between both. I would pick AFR's. But both would be a great choice.

Please no gt40 irons... Don't let these fools here trick you into buying some than spend money on valve springs/porting..
I really like AFR and trickflow products

A 306 to a 302 is the same thing. You will see an entire 5 HP gain from the 306.
If you can get a fresh 302 for cheaper, do it. Or just get a 351 as long as your picking a block.

The main reason for the 306 and head change can be for a higher or lower compression ratio make sure those valve reliefs are huge on the pistons then get the 185 AFRs and a nice custom cam

First off Do NOT buy a used engine. I don't care if the owner tells you that it just came out of the machine shop and has enough reciepts to carpet your room. Secondly, what is the purpose of the engine? Is this a max effort or a GOOD STREET SETUP? I highlight this to make a point. Less is more when it comes to making a street setup live. My advice;
Go to a Machine shop and tell them what you want. Have a pro build the bottom end and degree your cam (F,B1.7.. Whatever just make sure you have a good set of lifters and pushrods) Either the TW or AFR heads... flip a coin. I like them both. while this is going on pick up/do the following; 190 or 255 in tank pump and new fuel filter Pro M meter and 30 lb injectors have whatever intake you choose port matched. Wash and clean out your car including the engine bay. Sound stupid? cleaning helps to find potential issues before the installation. be thorough and realistic. look at the torque boxes and reinforce them BEFORE the new engine is installed. upon removing your stock mill, pray you dont damage any of the harnesses. Install and run the shit out of it. Save up for a transmission, you'll be buying one soon.
