Bad circumstances, but some good parts.

The heads are 4V with screw in studs and guide plates. Might be a good deal. I can't tell if they are open or closed.

The heads aren't 1970 with the 4Dot. Open/Closed who knows.

Actually the 70s are just the large 4 the 71-73 low compression use the 4dot marking system, so if they are just the large 4 they are correct 1970 4v quench heads good luck!

Not sure of your source, but my 1973 OC heads have nice big "4"s in the corners

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

I have read in the past that the "DOTS" are just casting marks thats why on the exact same heads some have them and some dont.

Well I have been racing and restoring early mustangs for the past 35 years and in that time frame I have seen many many cylinder heads and everyone of them with the dot is an open chamber low compression head. A possisble explanation could be that a racing organization would give weight breaks or penalties for the different cylinder heads in different classes. The dot is easily filed or ground off by unscrupulous people or lets say bending of the rule book, or even sell them on a car and say they are the High Compression versions when they are not!Undecided Been thru both scenarios-

I'm sticking with the "dots" are casting marks

http://www.stangnet.com/mustang-forums/t...gs.350201/

"as for the dot that just means you've got early 72 4v or earlier heads...ford retooled for the gas crunch after about february 72 and the dot dissappeared so odds are they are closed chamber heads."


here are more links than you care to read on the subject

The early 71 4V heads had 4 dot and closed chambers. Here is some pics of my early 71 4 dot closed chamber heads. I be leave it was mid 71 the compression dropped.
