Cheap 318 performance mods.
For a nice cruiser I have to say id rather do the 302 heads over 360 heads and just clean up the nasty in the heads (light porting) as yeah I know, 360 heads on a 318 have been done forever but a 318 is a bit low on compression anyway, I certainly wouldn't want "less" which is what plopping 360 heads on is gonna do for you...
