World Jr vs GT40's
AS ya'll know, im looking for iron heads to go with my new gt40 tubular intake.
I found a guy selling World Jr Heads that have been professionally ported ( he's including flow charts ) with springs for the f cam ( i have no idea what springs these are )
The valves are 1.94/1.60
I have been doing some research but there's no comparison on these heads with gt40s.
I was wondering what your experiences are with them?
He is asking 500 for the heads w/o rockers. Which is fine i have a set.
The only thing i have read thats bad about the heads is the port work, so if they have been ported i should be alright im assuming?
( Also, will world JR bolt up fine to a GT40 lower? )
Thanks for the input!

my buddy had the exact same setup. box stock tubular and started with mild ported gt40's, with a 125 shot he went around 11.60-11.90
swapped to the windsor jr's and gained some. he also went to a c4 so i cant for sure what he picked up... but it was worth it to him
match the heads to the lower... you may or may not see a little "step" where they meet
