The advantage of the 302C head is not on the track
By Styletone58 - 12/28/2002 11:08:31 PM; IP 216.244.14.214
The 302C "Aussie" head is simply a 2V C head with a closed combustion chamber. It's advantage is in allowing a quick and easy boost in compression on US 351Cs with dished pistons. This way, you can get a boost in power without having to resort to high octane gas, if the piston to head clearance is not too large. There is no advantage in port flow when compared to the 4V, anymore than any US 2V. In fact, the way the chamber wall is reduced around the valves as compared with US CC heads can hurt flow if it is not removed. The 302C head is great on mild street engines that need torque, where the extra compression and higher-velocity ports combined with a DP intake and a mild, fast-acting cam will make for a brad powerband. Go spinning around a track at 6100 RPM and naturally the 4Vs will excel. There simply is no question. Since when did the 302C head get this big "HI-PO" rep? It's a great head for a mild streeter, nothing else.

I do believe that the 351CJ, named I believe for the cam profile which is the same as the 428CJ as well as to make a marketable performance connection, should have been built using 2V heads and the Aussie 302C-4V intake. Would have been a snappier street engine, if the same CJ cam and converter been used.

Better opinions than mine can be found at the Cleveland forum:
