Anyone know if the edelbrock performer rpm heads are any good. I read about the rhs head and they seem good but seen those and wonder which will be better...Engine will be a .30 over 360(that's the first choice) I was also thinkin a .40 over 318....cam between a comp and crane....nothin that will max out the springs....2500-3000 converter....3.73 or better gears.....I kno the 360 will make more power jus throwin in the 318 to see what those opinions will be also....Any suggestions be appreciated..
