Lion Speed Head

In my opinion ,Charlie Yapp has done more for our hobby than anyone else I know. He is a great person and in no way should he be slammed by anyone on this forum. A apology is in order I cannot believe that a personal attack like this should be allowed. Bruce Newbery.
 
Bruce, you are so right! known Charlie for many years, great guy. those slammers and attackers should be ashamed of themselves,but have no backbone to admit wrong.
 
I agree, Charley has done a lot for the performance side of the hobby, more than any other as far as variety of heads and other performance parts offered. Besides that, Charley is a regular guy and nice to talk with.

I don't have a Lion head at this time. I have read the model A forums for the past fourteen years. From what I have read, spark plug threads that protruded in to the combustion chambers and other sharp edges were the problems that needed to be addressed. Sharp edges and exposed threads heat quickly and can cause pre ignition.

I believe that all of Charlies heads have machined combustion chambers instead of cast as suggested in a previous post.

I agree with you Bruce. Talked to Charlie some time ago on the phone. A true gentleman and a pleasure to talk to. Wish him the best.
 
I have a Lion 1 head that has never been used. After all, I have it so I might as well use it. I may go ahead and install it after deburring the chambers. I think it may work well with a B distributor and the dual carb Vortex intake I have for a little boost in power over stock. Anyone know what all should be done to these heads to improve them?

I am running the aluminum version of this on a old beater engine with new cam and valves. Single small Stromberg, 81 I think. Runs great, wish I had the iron version just because of corrosion, but I like mine a lot.
 
I also bought an early version of Lion Head III and had severe knocking.

I wish that I had seen this info posted here by Pat in Santa Cruz and Dave in MN and others before I sold the head. (Posts 3 and 14 ... there are others)

Shortly after the problems, I started using car in business and needed a stock engine without the problems that I was having.


So the "Head with the Large B" went back on the engine.

I needed money around this time and besides a fellow offered me $145 more than I paid for it a few months earlier!

I know a few folks running Lion IIIs today and they really like them. The owners or previous owners must have fixed the problems.
