Andrew, A W53 on the L18 would be at a guess somewhere around 10:1 so you'd have to use 98 octane and a cam in the 66-76 degree range to get the best out of it, also a recurve of the dizzy etc so it doesn't grenade to piston lands - nothing too dramatic from what I see from here. W53 chamber volume is 39cc, A87 is 41cc so you can work out the CR yourself - if the L18 is bored don't forget to allow the extra volume.
210 closed chamber heads were used on L16's in Aus towards the end of the 1600 production run - nothing special these, like small everything. They can be opened up port wise, but really why bother when W53 and reasonable A87 heads are still around. regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:membersozdat_owner@;datascribe.com.au]On Behalf Of Andrew Greenbury Sent: Monday, 4 November 2002 2:19 PM To: [EMAIL PROTECTED] Subject: cylinder head replacement cont... Hi everyone, Just wondering what people think about using a W53 head on an L18 block with flat top pistons - will the resulting compression ratio be too high?? Also, I have a 210 head at home, but the combustion chambers are closed but with 1.5in intake valves - any ideas of its origin?? I thought all 210 heads were open, while the SSS head had 1.65in intake valves - this seems a mixture?
