holley systemax intake?

They can be used with a 1250 but there will be a huge lip on the heads (intake port is bigger).

That intake really is going to give up a lot of power everywhere with a 302 let alone one with stock heads compared to a cobra/gt40 . . . just my $0.02
 
i know this i have a pro products one on it now but i sold it so i can buy the cam for my race motor and thats what my holley is normaly on but its just getting stuck on this motor for a short time so i dont have my car apart and not able to drive it
