59AB head
 

Does anyone have a loose 59AB head they can measure with a caliper. From the top of the stud hole (where the nut sits) to the mating surface at the block. I want to install aluminum heads but if I have to replace studs I may rethink. I may open a can of worms.

Re: 59AB head
 

There are at least two, and maybe three different stud lengths. Long at the top, short at the bottom. The French motors have two bolt lengths, so two different lengths at least.

Some aftermarket heads have different stud lengths to stock.

Unless they are Ford aluminum heads( Canada made or Denver heads), you will have to replace the studs.
Which heads are you thinking of?

Re: 59AB head
 

I will probably end up with Edelbrock or Offy. They are just shy of 2". I wouldn't mind finding a little more vintage though if they don't cost an arm and a leg.

Re: 59AB head
 

They will cost an arm and a leg and most likely more! Also unless they were well taken care of corrosion well be an issue.

If your going with the new Offy/ Edelbrock heads ( which I have on my AV8) then Van Pelts sales has a kit with the proper washers/ studs / nuts. They fit great.

Speaking of vintage heads, I got a set of Evans heads for early blocks recently, cost me $800.intake was extra $300

Re: 59AB head
 

Edelbrock and Offy heads use the long studs/bolts in all the holes, Navarro heads use stock length studs in the stock locations, at least the old ones did.
There are three different length studs/bolts on stock heads.

Any idea what cc those Evans heads are? I want to avoid pulling studs if I can.It could open up a new can of worms. I have one Navarro head and it does look thinner. I need to measure.

Re: 59AB head
 

They have #s on them, I’d have to look again when I get home.

Number was 281, not sure what that equates to.
