ZZ4 cam change "drag car"

I have a ZZ4 350 that I am using in a 1800lb race car w/ 5500 stall converter, powerglide
trans, 4.10 gears, 31" tall tires, & also a 3200lb race car w/ 4500 stall converter,
350 trans w/brake, 4.56 gears, 29" tall tires. I am only temporary using this engine &
only want to change the cam with out any mods to the heads. I think max cam lift with
these heads & springs is .525" I also beleave there is not mutch to gain after .500"
lift with these heads in stock form. With that said does anyone make a HR cam with
.525" lift 240 or 250 dur. at .050 & 106 lsa. I know this may not be the best design for
max power, but would work for this application.

With the L98 heads and a heavy hydraulic roller valve trane, I wouldn't think their would be a whole lot of power to be found upstairs in the RPM band. The heads are more suited to lower RPM power and would be pretty mis-matched with a cam that makes power up high enough to work with that stall and gear.
