That’s what I’ll do. Already have washed it with lacquer thinner.

For what it’s worth, and just for general info if you care, from the JCNA Series I Judge’s Guide it looks like the head on your '67 OTS should be silver not gold:
CYLINDER HEAD COLOR Pumpkin colored through at LEAST engine number R-2518-9 (see footnote C). Gold colored to silver- At this point in time, 6-2013, we cannot state positively whether any E-Type titled as a 1967 had a gold painted head.
See page 8 for more info: https://www.jcna.com/sites/default/files/files/e-type1.pdf
Whatever you decide have fun with your project. 
Interesting. I thought since it was a 9:1 it would have a gold head. But-I’m still not sure the head matches the engine

Hey Larry:
Interesting, yes, particularly in regard to your other post concerning cylinder head ID where you mention your car # is 1E12806. I also notice you have it registered on XKEdata.com - your info shows 1E12806 was built in March 1966 but wasn’t titled until 1967. In your profile you show it as a 1967 OTS and that’s what I was going by when I referred to the JCNA guide. So going by the build date, not the registration date, there’s a good chance the gold head color could very likely be original to the car. 
And the engine block is from a ‘69. So - - -now it really gets messy! I’ll keep it gold to match the build date of the car. Why the title when I got it showed ‘67, I don’t know and never will. It was shipped the end of March ‘66 so it should have sold long before the ‘67s came out.
