Are these Alum. or cast heads???

If alum, ignore the rest

If they are cast and you have a true 10.5:1, you will have to pull some timing.

That is too much compression for pump gas and cast heads, especialy if those are reworked stock heads, they have a poor combustion chamber design are prone to detionation.

You can try some colder plugs, set timing too about 30-32 total and add a little fuel.

Good luck,
