Heads beautifully machined but the attached parts, most likely out sorced were in poor condition, we did leak down and then performed a complete valve job, tested springs, and found 4 exhaust valves not fully machined. Polished them and did triple cut reseat on the valves.

Worked better than I expected. If you’re planning on running this in a similar engine. Here’s what I did. When I receive the heads I thoroughly inspected. I compared the spring tension to the stock ones that I pulled off and the valve springs in these heads had stiffer Springs, also seemed pretty consistent across all of them. I got a felpro multi layer steel head gasket. New Chinese high tensile head bolts from eBay, Also didn’t realize that I couldn’t run the original rocker arms so I had to buy Chinese stainless roller rockers from Amazon, chromoly push rods and guide. The stock pedestal rockers won’t work as the threads on these heads are larger . No biggie, do the math to make sure you order the right push rod length. Verify with a marker on the valves and cycled the engine. I also did this when it was 30° outside.. so I’m gonna take the upper intake off and valve covers and re-torque everything in the spring. Anyways, it’s running good and pulls strong.

Its great for the price, and for a stock engine. But if for a modified engine it is a great starting point. Small modifications are needed. The castings are are a great starting point, the valves and springs are good enough for stock engine but not a performance one, plus runners need to be cleaned up at minimum or ported for performance eng. But it is still a good starting point

I loooove the heads my only issue is finding spark plugs for them. Only place had the plugs for these heads was Napa and they cost 140 for 8. The plugs are NGK 953594. Plugs need to have a 25mm reach.
