Is there a difference between the heads on a late 70's A1 1.6 head and an 82 MK1? Question pertains to a header swap. Thanks for your wisdom.
 
An A1 header will fit a 1.6, 1.7, and a 1.8. The head is the same on the 1.6 and 1.7. The A2 header is a different angle than an A1, so to answer your question, yes it will fit.

Case in point, the header that I'm running on my GP Wabbit with a 1.8 is the same header that came with my A1 Scirocco race car that I bought in 1992.

Hmmm, good info, I should probably purchase a header.

I've running the early rabbit manifold with dual downpipes and the motor seems strong regardless. With such a short time frame before next event (not to mention a thin wallet) I elected to port and polish the stock manifold which is now installed on my car.

Given the $300 or so cost of a header, is it worth much power over the early rabbit cast manifold.

Tim ,great idea. I'll go to tech to get the car weighed. If the motor and suspension work well, I might be a front runner :-) LOL. I sure would hate to get DQed for being underweight.

Given my last 3 performances, I should be ecstatic if I even make it to the race.

I'll bring a drill, some bolts and my "new" tool to loan you.

Once I bought a pace setter header for the 1.6 Scirocco. Advertised as equal length (NOT!!!) 1 3/8 primarys. Worked OK, probably better than a stock manifold, but not as good as my 1 5/8 true equall length header. But it was only $125 from J.C. Whitney.
But that engine ran great up to 8,000 rpm's.
