Dealing with a bone stock early model 260z. Has the low compression e88 head--- 8.3:1 I believe.

Is it a worthwhile upgrade to have the existing head upgraded to the bigger valves or should I just purchase an earlier lower cc combustion chamber head?

If a head swap, what is one of choice?

I want better performance but not an engine that requires higher than 92 octane.

Thanks

An N42 head seems to be the head of choice for a little more HP and strokers as well. If you can find an E34 they were high compression heads. I would definitely consult some pro DATSUN engine builders before spending any money. Good Lucl!

Dean,

If you want an honest opinion based on 30 years of race car building, go see Andy Pearson at Specialty Engineering in Delta. Anyone in BC will tell you he has probably forgotten more then most have learned when it comes to building Datsun engines.
