Re: Z head
I have one on my 1917. Dyno showed almost 22 HP at 1200 rpm and 26 HP at 2000 rpm. I'm very happy with the car's performance.

Re: Z head
I run a z head on my t's and have been very happy. My best experience was adding one to my tt snowmobile it made a huge power difference on a very heavy machine. I have had no negative issues

Re: Z head
Hi Marshall, There are lots of Z heads in use with good results. I have 2 of them and like them very much.

Re: Z head
When fitting a Z head you must check that you have piston clearance, more often than not you need to grind the head some. Power wise they are great.

Re: Z head
I'll second Frank's observations. there are enough differences between Z heads that each should be trial fitted before finally installing. I do this without a gasket first. Hand crank over to check for any knocks. Tap it back as far as it will go on the bolts and repeat. Tap it forward and repeat. On more than one occasion, the combustion chamber had to be relieved a little for the rising piston to clear. Once fitted, hand crank again to be sure.
They do give instant power and represent good bang for the bucks invested.

Re: Z head
Good advice Allen. Especially if you have large cylinder bores. My 27 is bored .080 OS and I beveled the pistons to achieve clearance on a Ricardo head.
