I have a set of 440-1 heads that I would like to get brought into 21st century.
Heads were originally ported/flowed by Muscle Motors in 2001, I am attaching the flow sheet.
I had to practically beg them over a 2 month time frame to send me the flow sheet. I have always had doubts that it is really the flow sheet for my heads, and not just one they pulled out of their files and sent me to get me off their back.

I have called and emailed Modern Cyl Heads, and Chad Speier but I guess they do not need any more business as they never returned my call or emails.

Heads are on my 500 cu. in. 8.71 blown/injected, on alcohol, dragster.

So I am looking for a good head guy.

Thanks
Dave
