I am currently in the process of ordering parts to get my 1.7 heads rebuilt-
the 33mm exhaust valves need to be replace so I am going to replace with 34mm. To go with the larger valves i need to get new valve seats and want to make sure i order the right size. Doing a search I can find 32mm, 35.5mm and 37.5mm and larger replacement seats - but it not clear if this is ID or OD of the - Has anyone has done this on your heads? if so which is the correct size to order? Thanks in advance for your input |
