Ok so I have searched and called ARP on this topic. What ARP head stud kit do I order for my LS/Vtec(B18A+B16)??? ARP didn't have a clue and tried to tell me to use the B18A/B ones, but I know thats NOT right. Searching here left me wishing I never searched. I found answers ranging from use the B16 studs to using the B18C1 studs...

So is it the B18C1 (11mm) studs???

For the love of god someone confirm this!!!

-They do not list an integra type-r stud as I checked (figured same PR3 head so why not the same studs, but yea...)
-They do list a B20 with B16 head but agian my block is NOT a B20

 

Get the gsr head stud set.

 

get the GSR/ITR ones (same thing). B16 headstuds are way too short, LS headstuds are the wrong length and 2 of them are way longer than the rest but the GSR/ITR is just right.

LS/B20/GSR/ITR all have the same block height. if your running a VTEC head on any of them youll be using GSR/ITR headstuds. B20's are exactly the same as LS blocks except of course the 84mm bore. GSR & ITR & B16B blocks are identical except their internals.

 

part # 208-4306

 

its weird...because arp part number 208-4303 is listed as ls/vtec b20/vtec conversion atleast at lightning.

I used GSR ARP's. Not sure, but I think that was mentioned in Bam's thread.

 

It is in Bam's...i also have GSR ARPs

 

208-4303 is the correct part number 100%

 

gsr is what you want, you can use the b16a studs, not the bolts.

 

Gsr

 

i bought mine off ebay and they were for a b20 with b16 head and im using them on my ls vtec build
