I tested a set of econo w2 heads that were Template ported. They peaked 273 @.600 220'
[email protected]. Just kinda meh.
Low numbers were soft. I did a lil touching at the top of the ssr and they went 291...by .700 .. lol... I told the guy I could fix them some...the turn needed real work down to it...but he thought he heard enough to go try it himself at home. Lol dummy never seen him again, got a text about him selling his **** and if I was interested.
Templates are worth 15-20cfm on all those heads. They don't really address much but keep you in the safe zone.
Most people can't control a grinder either..lol
