I know I can get these new from several sources but since I'm always on a shoestring budget I thought I'd see if anyone had something laying around they'd part with for a reduced price. Smile  
Looking for somewhere in the neighborhood of 9 to 9.5:1 compression with appx. 85cc heads. Going in a street car and needs to run on 91 pump gas.
I have new 521 .030 flat tops from the kit I purchased that are supposedly made by Wiseco with valve notches for both standard and SCJ heads. Maybe trade?

4.3 stroke. 6.8 rod.

Thanks guys.

You need a dish of -28 to -29 cc's to get 9.5 cr. and -37 to get 9.0. 1.450 compression height.
