Default Re: High Compression Head

That’s interesting
The Yapp Lion and Rocket heads are very close to some Briggs Jr drag heads
Brierley has a close Harley Davidson design
Both of these work very well
There are others that require changing pistons but are marginally better


If you want more go OHV
