Brand new fully race ported Formula Atlantic head from TRD. This means new, never installed, zero hours, no heat cycles, no excuses etc. No cams, buckets, springs or valves as this is a bare head. Great for that race project or excellent spare to have. This is for the Toyota 4 AG engine and could also be used for Ralley, Solo 2, SCCA, Vintage, or whatever hot project you are cooking up.
