Comp cams xe268h for 318
My 1999 KB catalog #006 lists the 107s at 502 plus 132=634
The 190s are listed at 581+132= 713, but they have a .050Quench dome, that you would have to mill some off to fit your chamber. These would make an easy +.005 deck height, and,.034Q with a closed chamber head, and maybe with careful pin selection, would be a very close match. At pistons .005 up and 63cc aluminum heads, this is close to 11/1 Scr. Factory J heads might drop that to 9.8.Pretty good number for iron.
ohhhhh, I forgot about incendiary devices.
