Valve angle change produces more cfm more horsepower by getting the 2.15 valve away from the cylinder wall. We can’t always stay with 50 year old technology if we want to close the gap on Chevy and Ford.
I still don’t bye into it. I say yes we can. We didn’t need it along with a huge valve and still flow well and make power. The option for it would have been better. Having it as the ONLY option keeps it expensive.
You can keep on praising it but most average guys can’t afford it or the expense that goes along with it.
Closing the gap with the other guys? Please. Let’s be serious for a few seconds. The only big thing missing was heads at an affordable level. Now it’s blocks & heads. When the W-7-8 were new, right there were your heads keeping up with the Jones.
