I have been wanting a set of heads for my mustang and i found a set on craigslist, they are edelbrock performer #6025. I want to put it on my 306ci motor i have a e303 cam and speed pro pistons will i have any piston to valve clearance issues or are they just direct bolt on with new head bolts and gaskets?

 

I had a set of 6025 5 years ago that had the 1.90 intake valve. They should just bolt on if they have that size valve.

 

they have the 2.02 1.60 valves

 

IDK, most wont fit with that size. i think trick flow is the only head with 2.0's intake that will fit.

but im thinking stock. IDK about your pistons.

 

unless the pistons are notched for it, I think you are going to run into trouble
