Hello everyone, i hope that i put this in the right place anyway, i picked up a 383 stroker motor and built turbo 350 for 1000 sounds great huh? Well before you ask how i know the cubes, i took the oil pan off and measure the stroke and bore. Anyway the heads are what i really dont know anything about. They are aluminum with no markings nothing, other than SR1586. They have perimeter valve covers I tried to put a victor jr intake on it and the when i started it up it would run very fast, like a vaccum leak. well it turns out the intake was not sitting flat on the heads so it was sucking air out of the valley pan. I have searched and searched and cannot find anything about them.

Thanks in advanced

out of the sbc scene now but i believe world products has sr torquer heads so since part number begins with sr, i would think they are world product heads.

and the 86 in 1586 prob has to do with sbc heads for use up to the year 1986 i bet....

I contacted world and they said that it sounded like theirs and to look under the valve cover for the casting number. So i will have to wait till i get that. But i did pull up the heads on jegs to look at, but i do not think these are torquer heads because the valves are parallel like normaly heads are. They are staggered. I will try to get a pic this weekend.
