Install 2.19/1.88 bowl blend and gasket match.

Thanks for that info. I have found two different sets of them now.

A stock set with stock valves and hardware for 300 or a ported set with the 2.19/188 valves and new comp springs etc. for 900.

I suspect it would cost more than 600 to make the stockers similar to the ones for 900?

If you are looking at the $900 set check out these on e-bay.
