EQ Clyinder heads vs 441 487 993 GM heads worth the cost
We can now run the IMCA EQ heads it will run us around a thousand bucks by the time I get them cut to 70 cc. We have 487 993 and 441 heads we can use. Our engine guy says for around 400 bucks he can cut to 70cc put new valves spring and screw in studs but we can not use guide plates. My question will the EQ's make enough extra power to justify the extra expense or will they make any more as I have read the 487;s are better . We are like most racers struggling to make it . Current motor has 487's on it . Motor rules are 4 eyebrow hypers smog heads cut to 70 cc 600 Holley HEI dist stock crank or scat\eagle replacement stock rods or stock type replacement 425 lift rule camshaft stock 1.5 rockers our current motor we turn 6500 to 6700 rpms I know we are out of this type engines power range as we are pulling much more gear than anyone else 662 on a fast 1/2 mile high banked track thanks in advance.
