ok so i'm getting my race heads back from the shop in a couple of days and i just now got my intake for the heads.i'm wondering if i could fit them on my l98 engine.i know its like 9.3 compresion and the l98 heads are 58cc stock and my heads just got milled to 58cc but i had the valves rolled on them from 23 degree to 20 and i got a .690 lift roller cam and some lifters sitting around.just my only fear is slamming my valves into my pistons and my valves run me 1300$ for a set of them.they are 2.12 and a 1.625 so who thinks i could bolt them on and not have any problems?

 

Im 99% sure you will slam the valves. The valve angle changed only 3*s, but thats a lot with an oversized valve and a huge lift cam on a stock motor. Im pretty sure the pistons are flat tops. I wouldnt want to waste the money to find out.

 

yeah.thats what i was thinking to i just figured i would ask.i dont know shit about the L98 engines.

 

Once you break it down to a shorty, theyre all the same.

 

Bust out the playdough. If the valve angle change doesn't cause a crash the increased duraton and lift or larger valve size probably will.

 

yeah the 690 lift cam in my eyes is a mild lift cam.its not like i would be using the new one i got coming witch is .792 and .786

 

crazy lift there. I would clay it and see. If its a stock bottom end than ur prob gonna run into trouble, get some of them forged pistons with like huge ass valve releifs in them, and than cut the releif deeper with a tool or something.
