Hey guys,

Long story short.. I blew a headgasket and now will be replacing wires, plugs, heads, cam, etc... not sure which cam to go with yet, probably a 306 or 305 ? Probably Lloyd Elliot or TPIS heads..

What are the best injectors I can have installed when I am having my heads / cam replaced ? Is this a good time to replace injectors ?

Also, should I replace the headgasket with the Impala headgasket or not ?

What are some other things I can upgrade while the heads are off etc.. etc..

 

Well... is anyone running more than 36# injectors ?

 

I've been using the Impalla shim head gasket (.029 compressed height versus .049 stock head gasket compressed height) since my rebuild in Dec 1999. No problems! Bumps up the compression ratio a bit of course. What kind of duty cycles have you been seeing on your scan/log runs? If you're above 85% duty cycle at WOT then, yes, go up on your poundage. Otherwise, why bother?

 

I would use the propper gasket to attain the compression ratio you desire.

How much were the heads milled? Do a search on dynamic compression in advanced tech and take it from there.

Injectors- same deal. bigger isn't better. You should be fine with 24# injectors and an adjustable fuel pressure regulator. I'd go with 30# and AFPR just incase you go bigger later.

Do what trey said regarding the CR.

I would get 30's to be safe. Your better off taking away some injector than pushing one to work.

 

So I am around 100,000 miles, is this a good time to replace the injectors or not.. ?

Also, where is the best place to get the 30# injectors ?

Jegs ?

 

cheapest way for new ones is to pick up a Fast Fords/Muscle Mustangs magazine and flip thru the online vendors. I've seen SVO 24# and 30# in there for as little as $189 a set before. More typically, you can find them from time to time for $209.
I bought mine from Tommy Vaughn Ford here in Houston for $209 and he's an advertiser in FF/MM.
