408 Stroker Help

Yeh grows out of hand really quick. Looks like I am going to check out the victor Jr heads. Found one in Amazon new for about $517 so ordered it and will take a look at it. I am sure the AFR are a bit better but looked at the flow numbers and the Vic JR is just under the AFR 205. Save some money with them to put elsewhere. If I don’t like the looks I can always still change my mind. The AFR 205 will need to be custom ordered with springs for the hydraulic roller.

My reason for going with bigger heads was to not need as big of cam to meet the desired 500 HP and not sacrificing low end torque with a bigger cam.

Well think i will go with the AFR 205 after all. Now I need a rotating assembly.

I've always believed the hype about big heads killing bottom end torque too because it made intuitive sense to me, but with modern build components, I wouldn't hesitate to run the bigger heads, even in a flat-torque application.

I agree, my 438 with AFR 220 renagades(largest inline offered) heads makes 475 foot pounds by 2500rpm.
