040 heads with 40x35,5valves and dualsprings with chromo retainers - matchported and flowbenched. 2nd hand only 300miles on them
What are they allow to cost?040 casting is a original vw type casting, but it isn't that good for porting like the 043 (more meat) do they? to me the 043 has way more porting oppertunties compared to the 040 because they don't have the guideboss so far in.
I was already almost done with one 043 head, but now i got this deal on the 040, what shall i do?
Thanks!!
