Low 60s better be a stout 582. If it’s a new build why not go bigger

Just would rather have 4.375 stroke rather than 4.75

is this in denvor nc or denvor co? co will be real tough with a 582!

Id go with sr20 if your willing to run gas. you'd need a stout 582 with HHs to run low 60s at 1900lbs imo.

This would be my choice, bad ass cylinder head and they have all the valve train geometry worked out so it is extremely reliable

Sorry, Conventional 24.5 heads on my 588. I use a 4.375 stoke to get 588 out of a short deck block.

I think if I was going to build another 588, I'd go straight for an SR20 build.

Look up the video on the X-20 head. If I were doing a conventional head that’s what I would build. Good luck with whatever you pick!
