We run some 305 heads on some of our IMCA motors..they work fine. If your gonna turn them up, you have to do some port work, but in your RPM range, you should do fine. Sometimes on the heavier cars, you need a little more air flow to turn a few rpms more to make them work effectively. I dont know your rules, but the cam and heads have to work together, if your on a cam rule, then the work on the heads isnt going to make as much of a difference.

What are the casting numbers??? I don't have my book with me but someone should know of a website to look up your numbers.
