help with mopar #302 heads

does anybody know if the 1985,86 318 heads #302, will bolt onto a 1977 318. i know these heads have larger pushrod holes, will this cause a problem?

All of the 318ci 302 cylinder heads will bolt onto your 1977 318 engine. The pushrod holes will cause no problems. they are just bigger holes. The 302 heads were put on all 1985-91 318s with 2 barrels. hope this helps. I just put a pair on my newly rebuilt 318 and they work great in my ramcharger
