185s Piston Choices

[79fordblake]

Soon I will be ready to have the cylinder on my 185s bored and a new piston fitted. It has a 200 cylinder on it already and bored to 65.50 with a 10.25 compression piston but has piston slap and is starting to burn oil(previous owner had it bored wrong or put in wrong piston)

I was gonna have the cylinder measured and see if a 66.00 piston will work. I can't decide if I want the Weisco 10.25:1 or 12:1 piston. Anybody know the actual compression ratio of the pistons in the engine?

I figure the pistons don't have as high compression ratio as they say they do but I may be wrong. I don't mind running 93 octane but don't want to have to use race gas. Is there a thinner head gasket to bump the compression up a little more with the 10.25 piston?

Thanks for any help.

id say stick with the 10.25:1 piston. ive had 12:1 and 10.25:1 im my 200s and the 10.25:1 was so much better. mine was bored 3mm (the max without resleeving the cylinder) and 12 was just too much for the head gasket to take. i went threw at least 3 head gaskets in 4 or 5 months. if your gunna bore it have it bored to the next size and go with the 10 rater than the 12 . the 12 also requires higher octain fuel as well.
