I race with an A12 because I have lots of parts and because up until switching to Vintage I had to have an A12 per the rules. Now that I can choose I will put in an A14 eventually, in the mean time I will use the GX bottom end with the H-prod Head with Weber DGV carb. So your plan of runnig the A12 into the ground and building your A14 is a good one , althought it may take 5 or 10 years to kill the A12!!! I have been racing with the same bottom end since 1991.
