s2krazyyy Posted August 18 Share Posted August 18 (edited) Looking to rebuild the l26 that came with my 260z. In terms of build I am not looking for the most HP, just something that has great throttle response. I was reading Datsunzgarage and his modifications on his shaved p79 head with f54 w/ flat tops. In theory I was thinking this could also work with the l26 since it already has flat top pistons and from reading his site the P79/P90 heads work well with Flat tops. I was reading another thread on here and valve clearance was a possible issue but wasn't confirmed. Is anyone running a shaved p79 or p90 head with an l26 bottom end? P79 mod: shaving the head .080" - installing 1975-78 L28 valves which have .080" longer stems - shimming up the cam towers .080" - shimming up the spring bases by .080" Thanks Edited August 18 by s2krazyyy Quote Link to comment Share on other sites More sharing options...
