Head Gasket Question

Hey guys, I have a stupid question. I am rebuilding a ford 289. My block was bored .030. My question is do I need a 4.030 head gasket?? Summit sells gaskets by the bore size, Jegs offers head gaskets that say 4-4.100. I talked to a guy at a swap meet today that was selling gaskets and he said it doesnt need to be the same bore size but I think he was just trying to sell more parts??? Any help would be appreciated. Thanks.

Just use a standard gasket unless your really trying to equalize all the cylinders, say like NASCAR or INDY or TOPFUEL.

Just use standard gaskets and get on with life.

Don't get caught up in the bull**** that the aftermarket would like you to.

Many of us have been doing it this way for many moons and have never had a problem........

Standard gaskets are 4.100 to accomodate a .060 overbore.

When installing those gaskets front means front. If you will look closely at the gasket near the front lower head bolt you will see that the head gasket has a square corner, and the rear end of the gasket does not. That square corner protrudes from under the head and is an easy way of seeing if the head gasket is installed correctly.

If I were you, I'd make that 289 a 302. Most machine shops will swap the crank and rods even-up. Use the 5.0 type pistons and rings, matched to your heads/compression. That is an easy 15 hp for no extra money. Shoot for 9.2 compression.

Consider early 351W heads and pistons/compression to match. That's another 15 hp for almost nothing $$. Stock W heads sell for $ 25 each and have larger valves and 15 % bigger intake runners. (144 cc vs 124 cc runners// but 60 cc combustion chambers) This was the hot ticket in the 70s for 289s but lowered the compression ratio when used over stock pistons.

For another $100 over a 289 you could have a 302 with an additional 30+ hp.

Been there, done that.
