Does anyone here know if stock 351W heads can go on a 289 stock engine? I know that 351W heads would have bigger head bolts, but as far as compression due to bigger combustion chambers on the 351W. I think 289 heads are open chamber, but I'm not sure if the 351W heads are the same or not, but if they are closed chamber would I face any concerns there, such as needing bigger gasket or anything. Thanks for help!
