So, im in the final stages of a Cosworth n/a engine build.
Using Farndon rods and Wossner raised top pistons. The head has had a skim or two and currently working out compression ratio. Im aming for a sensible 10.5:1. Its not a big power engine.
I see Burton do a range of MLS head gaskets right up to 140 thou. Selecting a thick gasket would give me some adjustability in getting the correct ratio. I havent done the maths fully yet but recon Im going to need a thick gasket.
The other option is machining the piston valve pockets but would rather not if I can avoid it as calculating true volume can then get complicated.
Has anybody had any experience with these thick Cometic gaskets? My thinking is they must be sound otherwise a good reputable company like Cometic wouldnt make them.
Lastly are they re-usable or is it a myth? internet search has mixed opinions, Again any actual real proper experience anybody?
Thanks in anticipation.
