    The cover bolts are 1/4 UNC and not the same as 6mm, the baffle bolts on mine were a self tapping type thing with spring washers, I also used loctite on them. Don't do the valve cover bolts up too tight either or they tend to leak. Why do you need longer bolts?
    Edited, the baffle bolts may even have been phillips head self tapping screws, will try and check. Oh and yes you should fit the baffles or it'll **** oil out of the breathers

    I'm fitting these ignition wire separators so they run down the side of the valve covers, with the larger thickness of the covers and new Gasket the bolts I have are too short

    I would just make sure they're not tapered self tapping screws, you don't want them falling out. For the bolts I find Spalding Fasteners pretty good, Great deals from spalding-nut-and-bolt in UNC- | eBay Shops

    Yeah they are similar to the crap ones I got but without the blade on the bottom,

    My PCV and oil fill cap are nice and tight tight in the valve cover holes so would I still get oil coming out if I don't fit the baffles??

    The PCV should be OK but assuming the oil fill cap has vent holes underneath then it'll fill with oil and leak over the cover. You need some sort of breather or the crankcase will pressurise and possibly blow a seal or gasket, I'd persevere and fit them, did you fit the washers and if so can you carefully drill the holes a bit deeper?

    OK cool no worries thanks, yeah I'm going to go down to my Dad's tomorrow and drill them a bit further

    Would a tiny amount of high temp RTV work on the screws to help secure them??
