Cylinder Head Choice

I appreciate the help here! I don’t know what a good converter is, but my budget is around $1000 at the top end for a converter. I don’t mind putting $5-8k into the car over a period of a year or two if it means doing it right.

I haven’t even put the cam into the car, or even taken it out of the box. I don’t mind returning it and getting something better - I would just need a suggestion as to what to get.

The goal is a 10.5 quarter mile.
Woahaw, speedster! 10.5 in the 1/4 mile changes a lot of advice folks will be giving you, including me !!!
