Cylinder head ID?

[1970artcarrjavelin]

I just got a 70 javelin sst 390 from my uncle. My grandpa bought the car new in 1970 and put about 16000 miles on it before the he got bit by the racing bug. The trans and factory rear end were modified by Art Carr, and the engine was built by a speed shop in california. I was wondering if anyone here could tell me how to I.D. the cyl heads, from casting numbers and such?

Welcome aboard...yes look under a valve cover for a 7-8 digit number and post up

Welcome! As MC said, look for a number between two valve springs. Post them here and we will disect them for ya. Did you make it to the AMO show this past weekend?

the #'s on the cyl head are 3216090-1

6090 is a single rocker head early seveties....not especially rare just harder to find. 58cc volume dogleg exhaust 72-73

Thanks, are these heads good for performance? I'm thinking about doing a little port work while they are off. What would be a better head but still keep the engine period correct?

Hey man, if you ever want to meet up, I could swing by and show you were the #'s are on your head. I am about to move to the area and am actually living at working at the Hilton that was the host hotel in Norcross. Drop me a line if you want!

Port work always helps....maybe remove some flashing and smooth out some areas

[Lifted79CJ7]

Port has always done well. Stern (sp?) on the other hand....how usless is that!

You've got a really sweet ride there - but you need to get rid of that 'one_fast_camaro' crap though and go with the original muscle car. The Jav's set the pace and the bar on the muscle car scene. Be proud of it =D> Besides, it'll run the crap out of any Camero =D>

OH and keep the 8-track in a box if you replace it. If / when you are ever foolish enough to sell it, the original parts and receipts (and stickers) will bump the collectors value $5-10 grand!!! ( I work with an antique car buff that does this as a "hobby")

I fully intend to keep this car and bring the engine back to life in a more pump gas friendly version however. But about my camaro, if you look around at that site, it is dominated by the mustang guys, most of them are a good bit slower than my camaro. I think I have the best of both worlds now, a very fast racecar and a very fast soon to be hitting the streets again javelin, my wife just doesn't like the loss of her spot in the garage(LOL).I love all the older cars though except the coupe mustangs and the early baracudas there isn't alot you can do for them.
