RE: Z series heads

[E Smith]

Valves are the same in both Z18ET and Z20 heads. 42 inlet 37mm exhaust. Ports are identical in all Z heads except for Z20E with split (2 piece)  inlet manifold x S110. Z24 have different port sizes but still same valves.

I am wondering whether I should use Z18ET head and cam, or Z20 head with Z18ET cam for my L/Z combo...I figured the Z20 would have larger valves?   Dave --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
