I recently purchased a set Edelbrock E-street heads and I'm not sure whether to use the performer 289 intake w/ a 1" spacer I'm using now or switch to an early f4b hi-riser. This is a 1973 302 w/8.5 to 1 compression ratio and a mild cam. These heads work in the idle to 5500 rpm range. I don't want to lose any low end torque. Any thoughts would be greatly appreciated. Also are all stud mounted rocker arms considered adjustable ?

Both of those intakes are really too small for use with those heads. Those heads are basically Performer heads with light duty valvetrain components.

Yes, at least when it concerns aftermarket heads.

Either of those would work a lot better.

Like the PRM intake as well for a nice wide powerband . More room to grow in the future should you decide to increase compression and have a lerger street cam.
