Hi I have for sale a pair of Vw aircooled cylinder heads machined to take 90.5 mm barrels and pistons (1776cc).
They have also been Semi hemi cut. Both are in good condition and are fitted with single heavy duty valve springs.
They are machined from 040 castings and therefore have 32mm intake and 35.5mm exhaust valves.
I am not using them on my project.
Any questions, please ask.
