Head Studs choice?? arp L19/map A11'/magnus HDs

[codeofdastreets]

Im building a motor and im not sure what head studs to go with..I know boost levels on c16 will be about 35psi or more so I defenity will not be going with a standard arp..Choice"s are arp L19"s,map A11's, or magnus HD's..

Plenty of people made great power on standard ARP head studs. But anywho, either one of those choices will work just fine.

They always work until they fail...

I went with the L19's and it's definitely great to have the piece of mind.

Regarding A1 and L19 studs; either one will work. They are the same material and will perform the same. Buy whichever is cheaper.

You mean the car you bought had them already, right?

English Racing recommends 6 bolt ARP's for 6bolt block/7bolt head builds unless you just want to plunk down the cash. They stand by their head surfacing techniques.

If you have the cash and are planning on a wild build then by all means go big.

If boost levels are past 32lbs, Iwouldn"t use a standard arp head studs.. I've seen standard headstuds streach..

Pretty sure I purchased and installed the L19's when I did the HG job.

Phunny, what type of hg did you go with?

What turbo are you planning on running? More than likely, standard ARP's and a composite gasket are more than adaquate. 35psi alone won't put a gasket out, detonation will.

I've been well over 35psi on standard ARP's and a felpro composite.

I'm pretty sure you'll deform the head before you'll stretch standard ARP's.

Permatorque. And the HG failure was due to the standard ARP's stretching.

I went with the arp l19's.

You blew the HG

Question is what took place to make them?
