MJ, quick question...

Do you polish your cylinder heads? i.e. the domed combustion chambers?

Just wondering as dad well telling me that him and his brother used to do this back in the 60's when they were racing?

Any chance of a piccy of em?

Cheers

Nate

i do, not as a performance enhancement but because im extremely sad and dont have many freinds. real reason... it helps to minimise the amount of carbons deposits, not too important on a racer as its stripped regular/revved hard so a majority of mixture is burned cleanly but always nice just to wipe the domes clean rather than chip away with bit of hard plastic.

fine grit wet/dry start with 600 up in stages finally 1200 and then autosol. be very careful not to rub the gasket face though. use the paper with water. takes a good bit of effort but worth it if you ask me. if youve seen dave cooper/vhm/couger red etc heads you will notice they all have a mirror finish though probably a marketing excersise partly? they do look nice though!

Was thinking I could clamp the old head gasket in place so as to protect the surface a little...

could do, maybe tape the gasket face up with parcel tape. sticks like hell and i use it for sand blasting similar items. a pain to get off though, thinners is handy at doing this as is petrol though thinners is much more effective... and more flammable so be careful
