primergray4x4 said:Right now I have a set of stock 88 350 heads, they used the same valves but don't produce the same bottom end power that the 487x heads did. I've had to put the stock springs back on the HEI dist. My motor was built so that everything was matched. I just knochted the center two bolt hole on the intake to allow for the differnt bolt pattern in the middle. Please keep me in mind if you want to sell them. I believe they came off the 70-72 327 vett's. Best of luck with your quest on finding the right set that you want.![]()
