you need a long reach plug for those heads, I ran those on my 540's NGK R5671A-7 will work for a starting point, what carb or TB efi is going on these.

Mine was tuned with NGK V power 7 if I remember correctly.

Thanks I'm going to use the Holley Sniper 800 cfm

Well made the 1st pull today, 548 hp / 576 torque @ 5000, need to add more fuel but so far everything looks good.

Nice numbers. Curious on ballpark what a build like this costs?

With new JE pistons, and AFR heads H-beam rods, ported intake Victor Jr, balanced, cam, basically only used the block & crank, with dyno time right at 11k
