I reused my TFS 215 heads on my 418, and unshrouded the valves to match the .040 Cometic head gasket (11.5 CR). EPS supplied the 234/242/.600/.615 117+2 camshaft that drives 10x better than the 234/242/.600/.610 114 cam that I put up for a year.

The new cam has 4* overlap vs 10* of the old cam, still has stupid bottom end power and has more mid range to top end power due to the earlier exhaust valve opening.

I have BTR Platinum springs with Ti retainers and Yella Terra Ultra Light rockers.

No dyno numbers, but I'm sure I should be ~525 RWHP in my M6 2001 ZO6.

Stock oil pump, Mamofied 90/90 intake with a Black Wing air filter. LG long tube pro 1.75" headers, high flow cats, 3" exhaust with LG 3" mufflers & over axle pipes.
