Hello Stahlsfarm: Its Rob here.
I have had a nice bunch of replies to my questions re the ribbed head being
high compression?
Very interesting indeed.
Some people have never heard of it !
Some people have it associated with High Altitude !
Some people said it does not exist !
Some peole have given the actual compression Ratios as being -
Std.: 6.9:1 Hi-Comp. 7.4:1
About 1/2 a point.
So, I have enough info., to make an informed judgement that I should bolt on
the high compression head ...and then you come along and say, that "your 3
heads, all look the same " !
Well Now I'm forced intp two more actions.
1]
Take my std. head off and measure it against my ribbed head !
2]
Wait for more conclusive OR inconclusive information freom other listers
before this thread dies a normal death.
Thanks again to all who responded !
