Any issues with bolting E7's to vintage motors?

[Glen's 1965 5.0]

Aren’t the E7 bolt down rockers that go with a roller cam??? Will that be an issue to overcome?

You Don't have to run a roller cam with roller rockers. You may be confusing roller rockers with roller lifters, two separate components of the valve train.Roller lifters ride the cam lobes. Roller rockers convert the upward motion of the pushrod to downward force on the valve.

must drill six 1/4 inch coolant holes in block to realign with new head.

u sure about that one? I put a set of thumpers ported e7's on mine with no problems...

I think it is the other way around... to put a set of 289 heads on a 5.0 block, you have to drill the steam holes in the block!! the 5.0 heads ( E7s ) are a bolt on interchange as far as coolant!! cool??

Just me............................

Yea, late model and 351 heads will bolt to an early block no problem. coolant holes"steam holes" will not be aligned. doesnt mean that the engine will over heat, just reduced coolant flow between heads and block in the middle cylinders. its up to you.
