Frequently Asked Questions

Will it fit my 1990 350?

Yes. It fits the 1987–1995 heads with angled center bolts as well as the earlier heads.

Single plane or dual plane?

Choose this single plane for an engine that spends its time above 3,000 RPM. For street driving or towing, a dual plane gives more low-end torque.
