But I guess my (in that case) inferior head would work together with a new summit-head?
I found a used head on ebay, mercruiser one, where the other head was ruined (together with the engine I guess) because the engine was hydro-locked on that side. Seller guarantees no cracks and has tested with feeler gauge.
Looks to be in good condition. Price with shipping would be 280 + customs = 364 dollars. Compared with 521 dollars for JEGS (or 524 for same thing from summit) heads.
For the 160 I think I will be able to have the head resurfaced and if there are shortcomings with any of the valves (even if the seller, who is a mechanic I think, have checked them and says they are ok) have them fixed.
Question then comes to would a used mercruiser be better than a new "Chevrolet Performance 12558060"?
If I were in the US and the used head was 100 + 50 in shipping I would lean towards that. But now it is 100 + 180 shipping.
Thanks for all the help!
