When I say it will see the 1/4 mile about 3 or 4 times a year it would just be a fun pass down the strip durring the nostalga drags. It is mainly for the "cool factor" it is going in a 53 merc pick up that is built as a 70's custom.
I was running these heads on this motor for about 2 years with no problems, they have the big valves in them and have been ported on bolth sides. The pistons where on the low side at 8.66 comp.
Im not looking to set a new track record with this Im just looking to have some fun with it so if it is a dog I won't care that much.
