302 aussy heads fit a 351c?

Just wondering, is this a true statement?

"AUSTRAILIAN 302 HEADS WHICH ARE IDENTICAL TO FITTING 351 CLEVELAND WITH 2 EXCEPTIONS...THEY HAVE 2V PORTS .WHICH ARE BEST FOR STREET AND THEY HAVE THE CLOSED QUENCH CHAMBER OF TH 4V"

Id like to put them on my 351c 2v. Any help would be appreciated. Thanks!

They'll bolt right on a 351C, & you need an intake OEM 2 bl or aftermarket 4 bl intake designed for the 2V heads, the 4 bl intake for the 4V heads won't work.

They will bolt straight on.
They have 2V ports.
The chamber is smaller than the 4V closed chamber. ( When fitted to a 351 they give roughly 1/2 a point more static comp than 4V closed chambers on the same engine.)

Are they the same heads or is there a difference performance wise? The guy is selling them for 500 on craigslist. Good deal or bad? Thanks again guys...

Re: 302 aussy heads fit a 351c?

if you compare them to 351 2V openchamber heads they have the same port and valve sizes but a smaller combustion chamber.
They give a performance gain due to the higher compression they can give.
They have more valve shrouding than the open chamber heads but this can be overcome with some chamber work and a good cam.
By using the 351 73/ULP pistons that have the dish top with the 302 heads you get around 10.3:1 comp.
If you use 302 heads with 351 flat top pistons you get around 11:1 comp.
They work well with a bit of chamber relief around the intake and exhaust valve and a zero deck height with dish top pistons.
