23* pro-filer heads

[tnslider]

Has anyone used these pro-filer 23* cnc ported heads on a dirt circle track engine? Any feedback? Looking to use on a 400+ cubic inch. Here's a link https://www.profilerperformance.com/...ree-heads.html

Haven't used them and never heard of the company but you better be way over 400 inches unless you plan on turning it to the moon that runner is way too big

Pro FIlers are really good for the money. You won't go wring there but gotta agree to it he above the 235cc is way big. Think 200-215cc. Maybe 220cc.
