you can make plenty of power with less expensive heads.

are you using a carb?

supercharger?

nitrous?

the afr' 205's flow around as much and you can make over 600 hp with them on a 363 with just a carb if you run enough compression and they will cost you far less . . yiu can even go afr 215 which outflow the kaase heads by a wide margin . . $1900.00 . . you also have to buy special valve covers for the p-38 heads so it eliminates a choice of covers.

trick flow 11r 205 heads, small diameter valve springs . . $2000.

the edelbrock victor junior heads will also make good power but they are pedestal mount style rockers . . $1650.
