Just saying that I find it easier to bench shim heads after they have been overhauled ( unless they are screw and locknut adjusters ) be it car or bike heads I'm doing at the time.
Apologies to the OP if this is going off topic.
A few tenth's of a thou distortion when the heads on the Subaru flat 4 are pulled down can upset the valve clearances especially when using oversized14mm head studs for high boost applications on them.
I bench shim the heads for the engines I build at work and set them to the top end of the tolerances so when the
heads are torqued down on the crankcases, the clearances normally end up cock on in the middle of the spec.
Picked up a set of valve stem seals and a base gasket from Robinson's 2 weeks ago for future use - normally check their website every couple of weeks
to see whats been discounted.
Thanks for all the suggestions - always good to get real reviews instead of the manufacturers blurb.
Will see what I can pick up tomorrow and get cracking.
Any recommendations for a semi gloss black enamel paint which actually works and lasts - a lot of the decent older paints seems to have gone all eco friendly and dont last.
