head question about the 302's
for more info; use the search function type 302.
I have the # 302 heads on my 318, they have a small chamber,
which raises the compression compared to x or j heads,
or the stock 318 heads used for many years.
If the 302 heads are Not ported; the x or j heads flow more air.
What size engine are you running? what rpm range,
{or which cam and rear gears}.??
I am using the Mopar cam; and have the stock 2.93 gears { 3.23 someday}
P4452759 .430"/.450" lift, 260/268 duration.
