I believe the company sells some Dash inserts that might fix the bad spot on you dash plastic.

I just checked them out but none of those would fit my dash. The cut outs on them aren’t consistent with my stereo or AC.

I’ll keep looking.

I had another question.

My engine cast numbers are:
2780930-340-5

It’s from a 72 and I have some 360 heads with cast # 3671587

What are the best heads for me to get the best compression from my 340?
