4AGE 20V Head Studs?

[too_quick]

hmm interesting i sent ARP (well the agent here) a 20v head bolt and they said no can do.
they heaps of bolts that were the right thread etc, but all had a bolt head too large to fit the head.....

Could some on measure the gap in the head where the bolt slides down and then i can measure one of the nuts and see what the go is ?

[Sam_Q]

the clearence measurement? yeah I can do that, get back to you shortly on it

[Sam_Q]

ok my vernia says exactly 22mm

The nuts a smaller than that easy, Even the washers are smaller.

Dont see why they wouldn't fit ?

Can some one measure a factory 20v bolt ?

[Mr Revhead]

the issue is getting a tool around the nut...
not the nut in the hole

Sure is.

Anywho my 10mm multi-hex long reach socket is still smaller than 22mm in diameter.

Its a bit fiddly getting the washers over the studs in a 16v because of casting marks etc. Still keen for some 20v bolt measurements.

have not heard anything back from ARP as of yet, will try to get some 20V measurements for you ASAP. Got some with the silvertop head i picked up recently.

sorry man having some trouble getting there, I will be going on tuesday, I will see what I can do then

[RT40Corona4AGTE]

Yeah I am finding it hard to get time to do anything lately myself. I have had no reply to date from ARP either concerning this issue. I will try to get some measurements this Friday on my day off. . . . . fingers crossed that I manage to find time. . . .;-)

[Mr Revhead]

i did mention before that i sent a head bolt to ARP and they couldnt match anything.....

so, every high HP 20v i have supplied parts for has used the stock bolts and not one has had a failure that can be blamed on the bolts. and that includes some rather serious engines....
and they are cheap too. so i recommend you use the stock ones

I have to agree REVHEAD, i have my 20v race motor, pushing 200hp, i only use the stock head bolts with no fuss at all.
I think the studs may be just alot of hard work and money for no benefit.
