will J heads work on a 318? And many many more questions.

This shouldnt be that hard. Just use what you have. yes there is way better combos out there. but like you said you just want a driver with some romp and good sound. Use the later 318 heads, just port match them cuz that cam is a little bit on the large side for what your doing. Use the crowler cam and DEGREE IT IN. and you will be pleased with your combo or at least with you $ vs hp ratio by using parts you already have. If you what if every part you will end up with a w2 headed 360 stroker with a roller cam and $5000 later ya you will go fast but not everone needs a nascar motor!! How many 318s out there get drove 10xs more than the big HP motors. I drive my slant 6 valiant way more than my street strip dart. I wish I had an in between car like a stock smallblock with a good sounding cam for cruising and leave it alone keep it simple hey good luck with your build:-D
