Cool take some close up pics of the heads, do they look stockish? Did you fill in the name or grind it off?

Nice sounding engine.

Did not grind anything.

I see you went with the Indy X heads. Where and how much did they cost? Anything special done to them? Port work? Valve size? Details Details Details

Nice!! they do look pretty stock compared to the squared off aluminum chunk heads. BTW the dip stick handle was black originally.

On my particular combination, they picked up 2-3 tenths in the 1/4 mile over a set of similarly prepped, blueprinted OEM heads, both having as-cast ports. Main differences were 1.88"/1.60" vs 1.92"/1.625" valves and a few cc's less in the chambers. Your results may vary.
