Smile Re: Mixing Castrol r30 castor with synthetic oils

I wonder whether it might increase power to have some strong build up on top of the piston, since compression ratio for these engines is about 6:1 only. Would be great to figure out how to get it up to a decent 9:1, without having to for example weld extra material on top of the cylinder (people have done that since there's not much material to remove from the head to increase compression). Probably leaving the build up on the piston crown will help compression ????
By the way, I'm new in the forum, Hello to all of you guys !
