2 , both in excellent condition
1 a std 2 litre, the other exactly the same ( big ports, same valves) but has the 43cc combustion chamber instead of the 2.0l 47cc. This raises compression ratio from 7.8:1 to 8.3:1
$75 each

I don't think so.The smaller head may be off a 1600 TC

smaller chamber head may also be a 4G67 head too.

They are about to be sold on ebay for $45 and $55 as there were no takers here. The Hi Comp one raises CR for 7.8 to 8.3. and has the big ports. Rememeber the VR4 heads are the same as the NA ones ( watch port size). Anyway probably too late now. I will have another Hi Comp one coming up with a machined face ( that cost $150) and new stem seals and fully tested. On race car now.
