Re: 289 with 351 heads?
All Ford heads are more work than they are worth! HiPo 289 heads are the same across the board as normal 289 heads,they just have spring seats and screw in studs.351W heads have huge combustion chambers,over 289 heads,need domed pistons to get any compression back.All late model 302-351W heads have small valves and screwed up exhaust ports!!! Why waste your money on stock junk,by good aftermarket heads[no chinese junk],and be done with it!! ROY
Real Racecars have Three Pedals!
