i need to kno if i can use a PR4 head on a 96 P75 block witout any problems

 

should be ok, i have done it the other way with no probs

 

same head, bolts right up

 

why? the 94+ flow better

 

bought it from someone they said it was a 95 p75 only that the 94-95 kept the same pcv set up as 90-93 pr4's. the head says pr4 mine says p75 i kno the p75s arent exactly the same design as pr4s so i dont want to take my head off and mess ish up

 

Its the intake manifold that flows better.

 

i had a b18b block w/ b18a1 head

no problems!

 

^ same here..i have measured the ports of both and the 94+ does have a bigger port..and yes..i believe the 94+ mani. does flow better too..the only reason i have on the b18a head is because it was built...in fact..the stock ports on my old b18b1 is actually bigger than that of my PORT N POLISHED b18a head..but in a sense its not how big the ports are..its how nice the ports leadin to the combustion chambers are..

 

the heads similar, it will bolt up ad the pcv system is directly related to the block you run. the 96 block had the black box on the back eliminated.

 

yeah i jus wanted to make sure before i bolted it on because my 96 head has the p75 stamp but this 94 b18b1 head says pr4 so i was wondering whats going on but i guess it'll work i'm going to retain my pcv set up tho so ill keep my valve cover and intake manifold, thanks guys.

 

i have the same setup b18b1 block and pr4 head car didn t start but i think is because the timing but everything bolt perfect
