To be honest with you lil dude the best studs are the emo ones.
Basically the metal and quality was way better back then and the studs were rolled.
A rust emo puch stud is still better then a new after market one.
Don’t buy fatter studs you might run into complications if you wanna make up for room so ytge gaskets sits perfect on the ports and the piston is siting nice then use the mlm spacers. Treats puch counter sunk head has to be drill to fit the fatter studs.
