they heads are off of an 89 block

86 5.0L

87-93 had E7 heads stock

and 86 has the crown for the worst 302 heads ever [8D][&o]

Which head is the best depends on your ultimate goals for the car, the best head for a N/A engine is different then one for a F/I engine

Specs on the cam look pretty mild and with E7's I would expect you to be in the 200-220 rear wheel region...expecting more will be a let down. Upgraded springs and rockers will prevent valve float but the heads will restrict the advantages offered by the upgraded cam to a large degree. The overbore of .020 nets you aprox 0 gain over the standard 302. My guess would be high 14's in the mid 90's. Watch the 'large exhaust' you really don't want to go too large or again you'll hurt performance.

My old mustang at full weight and with only TB, and MA , on shi##ty street tires and stock susp would run 14.1-14.3 consistently. But the heads will be your down fall, save up till you can buy some. The cam is pretty mild, i think stock is .444, but like someone stated bigger intake and cam w/o heads will slow you down. My buddy got his stocker to run 13.998 with tb,ma, and good street tires. He put a f-cam and eddy rpm 2 on his motor with the same stock heads and his best time was 14.365.
