I know this is a stupid question!

I don`t want to sound stupid

but if header bolts/studs have to be sealed(because of water jacket) why use bolts? why can`t you use the studs already fitted?

Oh boy im up late...

my guess is that if you put on new headers its good practice to renew the bolts / stud while your there. Also if the old studs look tatty and you are going for the "eat your dinner off my engine" look

I can`t sleep so ,looking on american e bay! I suppose the question I`m asking is is it ok to use studs,or is it preferable to use bolts( clearance problems?)

thats right use the bolts so you have room for spanner/socket they have a very small head 7/16 or 3/8,. on some headers you can leave some off the studs in and fit a spanner on them it is handy like that cause you can hook the headers on them a lot easier, always use a little bit off silicon sealer on the threads to stop water leaks as you mentioned

Studs will hit the headers, have a look how close they are on your small block, even getting dedicated header bolts on that combination of head/header is real close !

i'm with duncan on this one, on all my previous cars (not sure whats on pinkie !) i've left a couple of studs in where its awkward to get at, and it has the benefit of letting you locate the header on the studs instead of trying to find holes that line up ! then i've just used the smal headed header bolts with a little silicone sealant on em, works for me !

As many Studs as poss, they have a shank that helps them seal, but always use silicon! works a treat
