So I just came across a old video where they put some trickflow 190 heads on a small block 410 stroker. I looked around on the web and it seems these heads are sold out everywhere I looked. So here’s the question and I know it goes along with how fast u wanna go,do u race and all that. But I only want to know if switching from a set of rhs la heads to these if I find them would be worth anything. Thanks.
