The PAC beehives are the best ones that I have tried compared to the Comp springs and some PSI springs (no longer available) We have used them on the 283 with great success. I weighed the old square springs and retainer were 26 grams heavier than the PAC beehives with retainer.
If anyone is going to othe Joliet Nats or Points meet, I will be at both. I have an old head with std square springs and the PAC springs to compare them too as far as spring pressure. (I have a spring checker too) I also have a digital scale if you want to compare weights.
I will have about 6 sets of the 1406s if anyone is interested at Joliet. I can give you a jobber price. First come first serve.
Look for the little green 66 Nova stocker. Jim.
